According to a first aspect of the invention, the object solves a volumetric flow meter for a piping system, for example in the form of a heat distribution system for a building, wherein the volumetric flow meter has a flow rate sensor and a signal sampling, wherein the flow rate generator has a radially projecting sealing element, wherein the sealing element with respect to a designated flow direction has a built-in path length, wherein the flow rate sensor is at least partially outside the built-in path length with respect to the flow direction.

Conceptually, the following is explained:

A "volume flow meter" is a measuring device for measuring the volume flow of a fluid, wherein the "volume flow" means a transported volume of a substance per unit time. Under a volumetric flow meter is to be understood regardless of its design, each device, which is suitable for determining the volume flow of a fluid here. In particular, a volumetric flow meter should be set up to determine the volumetric flow of a fluid which flows through a pipeline. In particular, the volumetric flow meter supplies the volumetric flow as a measured variable, which can be read and / or further processed electronically. The measured variable of the volume flow can in particular be read as a function of time and / or further processed electronically as a function of time. A volume flow meter essentially consists of a flow rate transmitter and a signal sampling. Irrespective of its viscosity behavior and contrary to the physical technical definition of a fluid, a "fluid" should be understood as meaning any pumpable substance, in particular gases, liquids and substances which become pumpable only after application of a pressure to be exceeded.

A "piping system" is a system consisting of one or more pipelines, which is designed to store and / or transport fluids.The components / system components of a piping system are, in particular, pipelines, pipe fittings, measuring systems, inlets, outlets, valves, expansion pieces, Fittings, gaskets, disconnect fittings such as flanges, fittings, fittings, couplings, and fasteners to support the piping system.

A "pipeline" means any body which is suitable for being flowed through by a fluid, in particular a pipeline may have a cylindrical shape or be composed of several surfaces, so that in particular a rectangular body is to be understood as a pipeline. which is suitable to be flowed through by a fluid.

A "heat distribution system" is a system that is configured to transfer and / or store and / or distribute heat, in particular, a heat distribution system is a piping system that is configured to be flowed through by a fluid.

A "flow rate transmitter" is any component or assembly that is suitable for qualitatively and / or quantitatively detecting a volume flow, In particular, a flow rate transmitter has a movable component whose movement depends on the magnitude of the volume flow.

A "signal sampling" is to be understood as a component or an assembly which scans the qualitative and / or quantitative signal emanating from the flow rate transmitter and converts it into a readable and / or electronic signal the outgoing from the flow rate sensor signal from the signal sampling scanned contactlessly.

As a "sealing element", each element is to be understood as meaning any body and / or any combination of elements which are designed to prevent or limit mass transfer from one space to another, in particular a sealing element is contacting or non-contact O-rings, flat gaskets or cohesive sealing elements have gained a high profile, but are not meant to be exhaustive here, but merely to be understood as an example of the quantity of the sealing elements, for example a spring ring arranged for sealing A sealing element protrudes radially if it has a radius which is greater than an outer radius of a flow rate transmitter This radius can vary with the circumferential angle of the sealing element the largest radius of the flow ssmengengebers.

A "flow-through direction" designates the direction in which a fluid flows through a pipeline system. <br/> <br/> In particular, the flow direction denotes the direction of the time-averaged partial flows in a flow cross-section of a pipeline system.

An "installation stretch" is the place where a body can be installed in a system, in particular the installation distance of a sealing element is the location where a sealing element can be installed in a pipeline system.

A "built-in length" is the extension of the built-in length.

A "separation point" is to be understood as a point at which a pipeline system can be separated opened a separation point between two pipes in a piping system and closed by attaching a Trennstellenverbindungselementes a separation point between two pipes in a pipeline system.

A separation point of a pipeline system is to be understood not only as the transition between two pipes in particular, but as a transition from a first system component and a second system component in general.

The pipelines on both sides of the separation point can thus be connected and disconnected with a "disconnect connector".

In particular, a separation point has a "sealing element", which is adapted to seal the separation point connected to a separation point connection element, so that leakage of the fluid from the pipeline system is prevented or attenuated.

Depending on the separating point connecting element used, different types of separating point are in particular screwed separating points with a screwed separating point connecting element, pressed separating points with a pressed separating point connecting element, plugged separating points with a plugged separating point connecting element, plugged separating points with fuse with a plugged separating point connecting element with fuse, flange connections and separating points with a bayonet coupling element. locking. The prior art has heretofore provided that systems for measuring the volumetric flow in addition to a flow rate transmitter and a signal sampling also have a housing for receiving the flow rate sensor and the signal sampling.

Such known in the art volumetric flow meter is integrated into a piping system such that the housing of the volumetric flow meter a right and a left separating point connecting element, in particular a screw connection with which it is respectively connected to the right and left partners in the pipeline system.

The installation length of volume flow meters known in the prior art is so great that, in the absence of the volume flow meter, it can not be closed with a conventional separation point connection element. In other words, for the installation of a known in the art volume flow meter ebendiesen or an additional connector, in particular an additional pipe with a length adapted to the Einbaustreckenlänge the volumetric flow meter length with corresponding components of Trennstellenverbindungsele- elements of the designated volumetric flow meter, for closing and / or for sealing the piping system.

Notwithstanding here a volumetric flow meter is proposed, which does not have its own housing. Rather, the volume flow meter proposed here consists essentially only of a flow rate sensor and a signal sampling, wherein the flow rate sensor is integrated into the existing piping system.

The volume flow meter proposed here can also be integrated with a separate housing in the existing piping system with a suitable design, this case has compared to the prior art no separate housing installation section with two Trennstellenverbindungselementen, but installed with the exception of its sealing element inserted inside one or more pipes becomes.

In particular, the volumetric flow meter proposed here is installed on an already existing system-related separation point of the pipeline system, with no additional installation section being required in the pipeline system. The installation distance of the volume flow meter proposed here is limited to the installation distance of a conventional sealing element, which is used in a system-related separation point. Since some system-related separation points provide an internal sealing element, the volumetric flow meter proposed here can also be realized with an internal sealing element in an advantageous embodiment, wherein an internal sealing element further has a built-in length, which, however, is not readily apparent from the outside of the piping system.

In concrete terms, it is conceivable, among other things, that the volumetric flow meter is installed or retrofitted to an existing system-related separation point without further device work. For this purpose, the separating points connecting element is opened at the existing separation point, optionally removed the existing sealing element and the flow rate sensor inserted into the pipeline so that the sealing element of the flow rate sensor takes the place of the sealing element of the separation point.

Specifically, in particular, it is conceivable that the volume flow meter proposed here in a heating and / or cooling system, a solar system, a drinking and / or hot water system, a heat and / or cooling system, a heat and / or cold collector system, a heat and / or refrigeration system, a heat and / or refrigerant exchanger system, a distribution and / or collector system, a tank and / or storage system and a pump and / or distribution system is used and is used in industrial and / or process technology.

In particular, the volume flow meter can be used concretely in a pump station, in a charging station, in a distribution station, in a heat exchanger station, in a fresh water station, in a home station and in a solar station.

Advantageously, can be achieved by the presented here aspect of the invention that the volume flow meter compared to the prior art requires fewer components, whereby lower costs can be achieved, a higher availability the volumetric flow meter and a correspondingly lower maintenance costs can be achieved.

Advantageously, the volumetric flow meter proposed here can be introduced into the existing piping system at an already systemic separation point by direct introduction of the flow meter in the existing piping system, which may advantageously result in no additional space being needed, no additional prefabricated installation section being required There is a need for an additional fitment in establishing the piping system, no additional disconnect is needed, no additional joint with additional disconnect connector is required, no additional cost for an additional disconnect connector, and no additional risks of leakage through an additional disconnect connector.

Advantageously, the volume flow meter proposed here can be retrofitted to an already systemic separation point in an existing piping system very easily and without additional effort, with no additional separation point is required, resulting in no additional risk of leakage, no additional space in the piping system is needed or must first be created, which compared to the prior art, no modification of the existing piping system is required, in particular no provision of an additional installation route and no provision of another separation point connecting element with the corresponding mating connection, whereby less time required for retrofitting and lower costs Retrofitting incurred.

According to a second aspect of the invention, the object solves a volumetric flow meter for a piping system, for example in the form of a heat distribution system for a building, in particular a volumetric flow meter according to the first aspect of the invention, wherein the volumetric flow meter has a flow rate sensor and a signal sampling, wherein the flow rate generator a radially projecting sealing element , wherein the sealing element with respect to a designated flow direction a Built-in track length, wherein the signal sampling is at least partially outside the Einbaustlängelänge with respect to the flow direction.

The prior art has heretofore provided that systems for measuring the volumetric flow in addition to a flow rate transmitter and a signal sampling also have a housing for receiving the flow rate sensor and the signal sampling. Such a volumetric flow meter known in the prior art is integrated into a piping system in such a way that the housing of the volumetric flow meter has a right and a left separation point connecting element, in particular a screw connection, with which it is connected in each case to the right and left partners in the pipeline system. The recessed line length of prior art volumetric flow meters is so great that in the absence of the volumetric flow meter it can not be closed with a conventional disconnect connector. In other words, a volume flow meter known for the prior art requires the same or an additional connection piece, in particular an additional pipe with a length adapted to the installation length of the volume flow meter with corresponding components of the separation point connection elements of the designated volume flow meter for closing and / or for sealing the piping system.

The proposed volume flow meter can be integrated with a suitable design with a separate housing in the existing piping system, this case compared to the prior art, no separate housing installation path having two Trennstellenverbindungselementen, but with the exception of its sealing element inserted internally inserted in one or more pipes.

In particular, the volumetric flow meter proposed here is installed at an already existing system-related separation point of the pipeline system, whereby no additional installation section in the pipeline system is required.

The installation distance of the volume flow meter proposed here is limited to the installation distance of a conventional sealing element, which is used in a system-related separation point. Since some systemic separation points provide an internal sealing element, the volume flow meter proposed here can be realized in an advantageous embodiment with an inner sealing element, wherein an inner sealing element further has a built-in length, which is not readily apparent from the outside of the piping system. In concrete terms, it is conceivable, among other things, that the volumetric flow meter is installed or retrofitted to an existing system-related separation point without further device work. For this purpose, the separation point connection element is opened at the existing separation point. If necessary, the existing sealing element is removed and the flow rate sensor is inserted into the pipeline in such a way that the sealing element of the flow rate transmitter comes to the place of the sealing element of the separation point. The signal sample can be attached to the outside of the existing pipeline with a simple connector.

Thus, the sampling of the measured value of the volumetric flow meter can take place on the outer wall of the pipeline system. In particular, the sampling of the measured value of the volumetric flow meter can take place outside the fluid so that the signal sampling does not come into contact with the fluid.

In a particularly suitable embodiment, the Signalabtastung can be secured with a cable tie from the outside to the pipeline and secured against radial and / or axial displacement.

In a further particularly suitable embodiment, the signal scanning can be secured with an adhesive connection from the outside to the pipeline and secured against radial and / or axial displacement.

Advantageously, can be achieved by the presented here aspect of the invention that the volumetric flow meter compared to the prior art requires fewer components, whereby lower costs can be achieved, a higher availability of the volumetric flow meter and a correspondingly lower maintenance costs can be achieved.

Advantageously, the volumetric flow meter proposed here can be very simply and without an already system-dependent separation point in an existing pipeline system be retrofitted with additional effort, with no additional separation point is required, resulting in no additional risk of leakage, no additional space in the piping system is needed or must first be created, which compared to the prior art, no modification of the existing piping system is required In particular, no provision of an additional installation path and no provision of another separation point connecting element with the corresponding counter-connection, whereby less time is required for retrofitting and lower costs incurred for retrofitting.

The comparatively very simple connection of the signal sampling with the pipeline can advantageously yield that the signal sampling is very easily accessible and can be maintained. In addition, the simple connection of the signal sampling is associated with very low cost, very flexible and requires only a smaller space.

The aspect of the invention presented here advantageously results in that the signal scanning can be retrofitted very simply and does not come into contact with the fluid, so that it can be made simpler since it is not designed for the action of the fluid got to.

Preferably, the sealing element is adapted to fix the flow rate transmitter relative to the piping system. Specifically, among other things, it is conceivable that the sealing element is a component of the flow rate sensor, wherein the flow rate sensor is installed so that the sealing element is located at the separation point in the transition from the first system component to the second system component. If the separating point is connected to the sealing element thus inserted by a separating point connecting element, the sealing element can be completely restricted and / or fixed in its freedom of movement. If the sealing element continues to be a component of the flow rate transmitter, then Also, the flow rate sensor at least radially and / or axially limited and / or fixed by the sealing element in the piping system.

With a suitable design is also conceivable that a flow rate sensor is fixed radially and / or axially via a sealing element in a piping system, if the sealing element is not part of the flow rate sensor, but has a variant of a positive connection and / or frictional connection.

It is specifically conceivable, inter alia, that a flow rate sensor is centered by a sealing element, so that a radial fixation can be achieved. In other words, the sealing element can be designed so that it can limit and / or fix the flow rate sensor in its radial freedom of movement.

In addition, it is specifically conceivable inter alia that a sealing element is designed so that the sealing element can limit the flow rate sensor in its axial freedom of movement and / or fix. Furthermore, it is concretely conceivable, inter alia, that the sealing element and the flow rate transmitter are designed to be coordinated with one another in such a way that the sealing element can restrict and / or fix the flow rate transmitter in its rotational freedom of movement.

This advantageously makes it possible for the design of sealing element and flow rate meter proposed here to integrate the flow rate sensor into a pipeline system without a separate housing, wherein the flow rate sensor can be inserted into existing system components of a pipeline system at a separation point, the separation point in particular may be systemic, wherein the sealing element is fixed by the separation point connecting element between the separation point and wherein the sealing element fixes the flow rate sensor in the piping system. Thus, no separate housing for the flow rate sensor is needed, which costs can be saved, which no additional built-in path length is required, which goes beyond the installation length of the sealing element, and thereby significantly retrofitting a volumetric flow meter is simplified.

Optionally, the sealing element is connected to the flow meter via a connecting element.

Conceptually, the following is explained:

A "connection element" is to be understood as any form of connection of two bodies.A connection of two bodies can be carried out in particular in a detachable and non-detachable manner, In particular a connection element means a weld, a frictional connection and / or a positive connection of two bodies.

It is specifically conceivable, inter alia, that the sealing element and the flow rate generator are glued or welded together. Furthermore, it is concretely conceivable inter alia that the sealing element and the flow rate sensor are connected to one another in a form-fitting and / or force-locking manner.

Advantageously, it can thereby be achieved that the design method of sealing element and flow rate meter proposed here makes it possible to integrate the flow rate sensor without a separate housing into a pipeline system, wherein the flow rate transmitter can be inserted into existing system components of a pipeline system at a separation point, wherein the separation point in particular be systemic can, wherein the sealing element is fixed by the separation point connecting element between the separation point and wherein the sealing element via the connecting element fixes the flow rate sensor in the piping system. Thus, no separate housing for the flow rate sensor is needed, which costs can be saved, whereby no additional built-in length is required, which goes beyond the Einbaestehenlänge of the sealing element, and thereby retrofitting a volume flow meter is significantly simplified. Preferably, the sealing element is multi-part. It is specifically conceivable, inter alia, that the sealing element consists of several components.

As a particularly preferred embodiment, it is conceivable, among other things, that a sealing element consists of an O-ring and a throat gasket. Among other things, it is conceivable that the flat seal seals the separation point and the O-ring makes a positive connection to the flow meter.

Advantageously, this can be achieved that the functions of sealing the separation point and the fixing of the flow rate sensor can be met by the use of standardized components in a simple manner and / or cost.

Optionally, the sealing element has a hole pattern. Conceptually, the following is explained:

A "hole pattern" means a design of the sealing element in which the sealing element has holes and / or the junction between the sealing element and the flow rate transmitter has holes due to the design of the sealing element.

This allows a suitable design that subsets of the fluid can flow through the sealing element.

The design of the sealing element can be used concretely such that the sealing element is adapted to seal the pipeline system to the outside, wherein the fluid can flow through holes in the sealing element in the interior of the pipeline system. In a particularly suitable embodiment is also conceivable that the hole pattern of the sealing element is designed so that the sealing element through the hole pattern has at its inner diameter an arcuate contour, whereby the sealing element loses stiffness at its inner diameter and whereby a clamping connecting element can be achieved, which is adapted to allow a detachable connection with the flow rate sensor.

Advantageously, this can be achieved that the sealing element in addition to its original function to seal the pipe element to the outside can also take over other functions.

Thus, it can be achieved in particular advantageous that the sealing element provides a connection element for connection to the flow rate sensor.

Furthermore, it can advantageously be achieved that the sealing element can be flowed through by fluid within the pipeline system.

Preferably, the sealing element has a sealing ring.

Conceptually, the following is explained: A "sealing ring" is to be understood as an annular sealing element, in particular, an annular sealing element may be an O-ring.

It is concretely conceivable, inter alia, that an O-ring can be used as a sealing element.

The annular sealing element, in particular the O-ring, can assume both the function of sealing the piping system and the function of fixing the flow rate sensor in the piping system.

Advantageously, this can be achieved by integrating the flow rate sensor with simple design features and through the use of inexpensive components without a separate housing in a piping system, wherein the flow rate transmitter in existing system components of a piping system at a separation point can be inserted, the separation point can be particularly systemic, wherein the sealing element is fixed by the separation point connecting element between the separation point and wherein the sealing element fixes the flow rate sensor in the piping system. Thus, no separate housing for the flow rate is required, which costs can be saved, whereby no additional chord length is required, which goes beyond the Einbaestehenlänge of the sealing element, and thereby retrofitting a volumetric flow meter is significantly simplified.

Optionally, the sealing element is eigerichtet to seal a separation point of the piping system.

It can advantageously be achieved hereby that the sealing element, in combination with the effect of the separating point connecting element, seals the pipeline system and no further component is required for sealing the pipeline system, thereby enabling inter alia a particularly cost-effective and easily retrofitted solution for a volumetric flow meter in a pipeline system ,

Preferably, the sealing element has a retaining clip, which is adapted to fix the flow rate sensor in the pipeline system.

Conceptually, the following is explained:

A "retaining clip" is a device which is set up to axially and / or radially and / or rotationally fix the flow quantity generator via a frictional connection and / or a form fit in a pipeline system.

Specifically, among other things conceivable that a retaining clip has a sealing element or is connected to a sealing element via a connecting element, wherein the sealing element clamped by positioning in a separation point and by the connection of this separation point with a separation point connecting element in the separation point with the retaining clip extending into the piping system and fixing the flow meter.

In concrete terms, it is also conceivable, inter alia, that a holding clamp, which fixes a flow rate transmitter, flows around and / or flows through the fluid in the piping system so that the fluid flows completely through the flow rate transmitter or partially flows through the flow rate transmitter.

Advantageously, this can be achieved that the flow rate sensor can be fixed using the retaining clip in a piping system, wherein the retaining clip has a sealing element, which can be fixed with a Trennstellenverbindungsele- element in a separation point.

Optionally, the sealing element is adapted to allow a designated bypass flow rate which can flow past the flow rate transmitter.

Conceptually, the following is explained:

A "bypass volumetric flow" is a subset of the total volume flow in the piping system that flows around the flow meter at the point at which the flowmeter is installed, while the other subset of the total volumetric flow in the piping system flows through the flowmeter.

Specifically, among other things, it is conceivable that a sealing element has a perforated pattern, wherein at least a part of the hole pattern is to be found radially outside of the flow rate sensor and adapted to flow around a part of the total volume flow in the piping around the flow rate meter, while another part of the total Volume flow in the piping system flows through the flow meter. In concrete terms, it is also conceivable, inter alia, that a retaining clip is adapted to be flowed through in such a way that part of the total volume flow in the pipeline system flows around the flow meter, while another part of the total volume flow in the pipeline system flows through the flow meter. It can thereby be advantageously achieved that one type of flow rate transmitter can be used for different pipe diameters and / or different sizes of one volume flow, since a balancing of the different requirements can be brought about via a suitable choice of the bypass volume flow. Preferably, the piping system is closed with a conventional separation point connection element, wherein the separation point connection element extends over the entire installation path length.

Thus, in concrete terms, inter alia, it is conceivable that a commercially available separating point connecting element is used to connect the separating point, wherein this separating point connecting element extends over the entire length of the laying line.

Advantageously, this can be achieved that a low-cost commercial Trennstellenverbindungselement can be used to connect a separation point, wherein a sealing element is fixed in the separation point, wherein a sealing element with a flow rate meter is directly or indirectly connected or a flow rate sensor, so that the flow rate in a piping system is fixed, the flow rate sensor does not require a separate housing to delineate the piping system.

Optionally, the piping system has an embossment, wherein the embossing is adapted to radially center the flow rate transmitter and / or to axially fix the flow rate generator. Conceptually, the following is explained:

An "embossing" is the result of an embossing process whereby during the embossing process a forming tool is applied with pressure to a part of the piping system, whereby the piping system is deformed resulting in a deformed part of the piping system compared to the undeformed one Part of the piping system on a relief, which is called embossing.

It is concretely conceivable, inter alia, that a part of the pipeline system is provided with an embossment and this embossment is set up to fix a flow volume generator radially and / or axially. Advantageously, this can be achieved that the flow rate transmitter can be fixed by a relatively simple embossing cost a few degrees of freedom of movement or the embossing can be used to easily clamp the flow rate transmitter during its assembly against the embossing, so that the flow rate encoder inexpensive some degrees of freedom of movement can be taken.

Preferably, the piping system has a rolling, wherein the rolling is adapted to radially center the flow rate sensor and / or to fix the flow rate generator axially.

The following is explained conceptually: "Rolling" is the relief of a rotationally symmetrical workpiece resulting from rolling.When rolling, a tool is pressed against the rotating rotationally symmetrical body, which presses into the workpiece a circumferential notch. It is concretely conceivable inter alia that a part of the piping system is provided with a roller and this rolling is set up to fix a flow rate transmitter radially and / or axially.

Advantageously, this can be achieved that the flow rate transmitter can be fixed by comparatively simple rolling a few degrees of freedom of movement or the rolling can be used to easily clamp the flow rate encoder during its assembly against rolling, so that the flow rate encoder cost some degrees of freedom Movement can be taken.

Optionally, the signal sample comprises a signal generator, the signal generator being adapted to emit a signal, the signal depending on the relative position between the flow meter and the signal sample.

Conceptually, the following is explained:

A "buzzer" is a device that is adapted to emit a signal, which signal may depend on defined influencing factors, in particular the relative position between the flow meter and the signal sampling. "Signal" is a sign having a particular meaning. In particular, a signal is an optical and / or an acoustic and / or an electronic signal.

Specifically, among other things conceivable that the signal sampling has a signal generator, the signal generator emits an optical signal via a light source, wherein the signal varies depending on the relative position between the flow rate sensor and the signal sampling and the signal is configured to indicate whether the signal sample is coupled to the flow meter or not. In particular, a flashing light can be emitted, which varies its frequency when approaching the signal generator and flow rate generator, a continuous lighting can indicate that the signal generator and the flow rate sensor are coupled. In concrete terms, among other things, it is conceivable that the signal sampling has a signal generator, wherein the signal generator emits an acoustic signal via a loudspeaker, wherein the signal varies depending on the relative position between the flow rate sensor and the signal sampling and the signal is arranged to indicate whether the signal sample is coupled to the flow meter or not. In particular, a beep can be issued, which varies its beep frequency when approaching the signal generator and flow meter, with a continuous beeping can indicate that the signal generator and the flow rate sensor are coupled.

Advantageously, it can thereby be achieved that the signal generator and the signal emitted by it make it possible to detect whether the signal sampling and the flow rate transmitter are coupled or not. In particular, it can thus be advantageously achieved in a simple and cost-effective manner that the signal sampling can be positioned on the outside of the pipeline system in such a way that the signal sampling is coupled to the flow meter, whereby the functionality of the volume flow meter can be made possible.

It should be expressly understood that the subject matter of the second aspect may be advantageously combined with the subject matter of the first aspect of the invention.

It is understood that the advantages of a volumetric flow meter for a piping system, for example, in the form of a heat distribution system for a building, the volumetric flow meter having a flow rate sensor and a signal sampling, wherein the flow rate generator has a radially projecting sealing element, wherein the sealing element has a built-in length with respect to a designated throughflow direction, in particular a volumetric flow meter according to the first and / or the second aspect of the invention, as described above, directly to a use of a volumetric flow meter according to one of the preceding claims for determining the volumetric flow of a fluid a piping system, for example in the form of a heat distribution system for a building, extend.

It is further proposed to fix the signal sampling of the volumetric flow meter from the outside at the point of the pipeline system corresponding to the flow rate transmitter and to connect the signal sampling with the data processing and evaluation unit so that the measured volume flow can be stored, evaluated and displayed there. It is also proposed to use the retrofitted volumetric flow meter according to the third aspect of the invention. It will be appreciated that the advantages of a volumetric flow meter for a piping system include, for example, a heat distribution system for a building, wherein the volumetric flow meter has a flow meter and a signal scan, wherein the flow meter has a radially projecting sealing element, wherein the sealing element with respect to a designated flow direction an installation length, in particular a volume flow meter according to the first and / or the second aspect of the invention, as described above, directly to a retrofit of a volumetric flow meter and / or a use of a retrofitted volumetric flow meter according to the first and / or the second aspect of the invention Determining the volume flow of a fluid in a piping system, for example in the form of a heat distribution system for a building, extend.

1125 through the flow rate generator 222 can flow.

The flow meter 221 in FIG. 24 essentially consists of a flow meter 222, a signal scan 223 and a sealing element 224, the sealing element 224 being fixedly connected to the flow meter 222. The volume flow meter 221 is mounted step by step. First, the flow meter 222 is pushed with the collar 227 and the sealing element 224 in the direction 234 in the pipe 226 until the sealing element 224 abuts flush against the pipe 226.

Subsequently, the pipeline 226 is positioned against another pipeline (not shown) or another pipeline system element (not shown), which is configured to be connected to the pipeline 226 by means of the male fitting 228 such that the sealing element 224 is fixed between the pipe 226 and the plug-in fitting 228, so thus also the flow rate sensor 222 in the piping system (partially shown, only the pipe 226 and the plug-in fitting 228 are shown) is fixed non-positively and positively.

1140 Next, push-fit fitting 228 is slid toward tubing 226 in direction 235 so that seal element 224 is fixed between tubing 226 and plug-in fitting 228 and flow meter 222 is frictionally and positively engaged in the tubing system (partially shown, only tubing 226 and plug-in fitting 228 are shown) is fixed.

The signal sample 223 is then positioned so that the buzzer (not shown) of the signal sample 223 indicates that the signal sample 223 is physically coupled to the flow meter 222 and connected to the tubing 226 at that operating position (not labeled).
