Definitions
- the invention relates to a device for determining a property of a liquid portion of a gas-laden medium, such as a density.
- Measuring the property of the liquid content of a gas-laden medium is a major challenge in terms of metrology.
- a Coriolis measuring device is used for this, as shown in WO2010129603A2.
- a first section wherein the first section has an angle of less than 20° and in particular less than 10° with respect to a horizontal.
- a closed end is arranged in an extension of the first section, with a connection of the second section to the first Section defines a beginning of the closed end, wherein at least one measuring device for measuring the property of the liquid fraction is arranged in an end region of the closed end.
- the closed end has an inclination in the direction of gravity, the inclination having an angle to the horizontal of at least 2° and in particular at least 4° and at most 15° and in particular at most 10°.
- a bypass line is provided, which is set up to connect the end area of the closed end to the second section.
- the bypass line has a valve which is set up to set a bypass flow.
- the flow in the closed end can be adjusted so that on the one hand the gas loading of the medium in the closed end is low and on the other hand a sufficient exchange of the medium takes place so that measured values of the property represent a current state of the medium.
- the closed end has a locking device, by means of which the end region of the closed end can be fluidically separated.
- the second section has a flow constriction, with the bypass line adjoining the second section in the area of the flow constriction.
- a negative pressure acts in the area of an outlet of the bypass line, as a result of which a flow of the medium through the bypass line is supported.
- the closed end has an inclination in the opposite direction to gravity, the inclination having an angle to the horizontal of at least 2° and at most 10°.
- the closed end has an arcuate section which, in a projection onto a horizontal plane, encloses an arc angle of 90° with respect to an arc center.
- the included angle is at least 45° and in particular at least 60° and preferably at least 75°.
- the arcuate section is arranged between the connection and the bypass line. The flow of the medium towards the bypass line experiences a centrifugal force in the curved section, which leads to an improvement in the separation of the liquid and gas components.
- the closed end has a cleaning device, by means of which a lumen of the closed end can be cleaned.
- the cleaning device has an ultrasonic transducer for generating ultrasound or a flushing ring.
- Deposits and dirt can be removed from an inner wall by means of ultrasonic waves. Deposits and dirt can be flushed away using a flushing ring.
- a dirt trap is set up in a starting area of the closed end, which dirt trap has a depression, for example.
- the dirt trap reduces contamination of the measuring device.
- the measuring device is a density measuring device and has a vibrometer and/or a microwave transceiver and/or an ultrasonic converter.
- FIG. 1 shows an exemplary embodiment of the device according to the invention.
- FIG. 2 shows an exemplary embodiment of the device according to the invention.
- FIG 3 shows an exemplary embodiment of the device according to the invention.
- the device 1 shows an embodiment of the device 1 comprising a pipeline 10 with a first section 11 and a second section 12 in the form of a riser.
- the first section is set up to accommodate a sometimes gas-laden medium.
- the device has a closed end 13 in which, according to the invention, a measuring device 20 for detecting a property of a liquid portion of the medium is arranged.
- the measuring device can be a density measuring device 21 as shown here.
- the density measuring device can have a vibrometer 21.1.
- the density meter can also have a microwave transceiver or an ultrasonic transducer.
- the second section 12 encloses an angle of at least 45° with a horizontal line, which can be 90° as shown here, for example, so that the second section runs vertically.
- a connection 12.1 of the second section to the first section defines a beginning of the closed end 13.
- FIG. 2 shows an embodiment of the device as shown in Figure 1, wherein the closed end 13 has an inclination in the direction of gravity, the inclination being at an angle to the horizontal of at least 2° and in particular at least 4° and at most 15° and in particular at most has 10°. In this way, an accumulation of gas in the area of the closed end can be prevented.
- FIG. 3 shows an embodiment of the device shown in FIG. 1, a bypass line 30 being provided which is set up to connect the end region 13.1 of the closed end 13 to the second section 12.
- FIG. 3 shows an embodiment of the device shown in FIG. 1, a bypass line 30 being provided which is set up to connect the end region 13.1 of the closed end 13 to the second section 12.
- the bypass line can have a valve 31 by means of which a flow through the bypass line can be adjusted.
- the flow in the closed end can be adjusted so that on the one hand the gas loading of the medium in the closed end is low and on the other hand a sufficient exchange of the medium takes place so that measured values of the property represent a current state of the medium.
- the second section 12 of the pipeline can have a flow constriction 12.2, with a connection of the bypass line 30 to the second section falling in the area of the flow constriction.
- a negative pressure acts in the area of an outlet of the bypass line, as a result of which a flow of the medium through the bypass line is supported.
- the closed end has a locking device, by means of which the end region of the closed end can be fluidically separated. This makes it possible to clean the end area at least in sections without interrupting the flow of the medium through the pipeline.
- the closed end may have an inclination in the opposite direction to gravity, the inclination having an angle to the horizontal of at least 2° and at most 15°. This can cause a build-up of gas Separation of liquid and gas fractions are better absorbed and discharged through the bypass line.
- the closed end has a cleaning device, by means of which a lumen of the closed end can be cleaned.
- the cleaning device 13.3 can have, for example, an ultrasonic transducer 13.31 for generating ultrasound or a flushing ring. Deposits or contaminants can be loosened and removed from an inner wall by means of ultrasonic waves.
- the closed end can be flushed with a flushing liquid by means of a flushing ring.
- the closed end can have a dirt trap 13.4, which is designed as a depression, as outlined here.
- the mud flap can be attached and removed by simple mechanical attachment such as screws. In this way, contamination of the closed end can be easily removed.
- FIG. 4 outlines an embodiment of the device according to FIG. 3, the closed end 13 having an arcuate section 13.5 which, in a projection onto a horizontal plane, encloses an arc angle of 90° with respect to an arc center.
- the included angle is at least 45° and in particular at least 60° and preferably at least 75°.
- the arcuate section is arranged between the connection 12.1 of the second section 12 and the bypass line 30.
- FIG. The flow of the medium towards the bypass line experiences a centrifugal force in the curved section, which leads to an improvement in the separation of the liquid and gas components.
