Description

10

The present invention relates to a device for determining weight or the contents of liquid gas bottles.

It has hitherto been difficult to use liquefied gas bottles that are filled with propane, butane, CO »or the like, for example are to determine the size of the contents if the bottle has been in use for a certain period of time has been. In such cases one would like to know whether there is one in the Industry, in the household, in the camping area or similar liquid gas bottle used empty, half full, full or the like. Partial filling.

The object of the present invention is to provide a device of the type mentioned at the beginning create, with which the content of liquid gas bottles can be determined in a simple manner ^ and in particular in design and manufacturing

is constructed or manufactured in a technically simple manner.

With the device according to the invention, in simply the weight of a fully or partially filled LPG bottle and thus the content of the liquid gas bottle can be determined in which the liquid gas bottle only has to be placed on the upper part of the device, so that depending on the im The pressure gauge shows the hollow body as a result of its compression. Advantageously, for certain standardized types of liquefied gas cylinders, the Manometer must be calibrated immediately in certain filling states. The construction of such a The device is very simple, since it essentially consists only of the two in the axial direction flat parts that can move relative to one another, between which the one with the incompressible Liquid-filled hollow body is arranged. On this hollow body is then a Commercially available manometer connected.

The device 11 or 11 'shown in the drawing is used to determine the weight of completely, partially or not at all filled liquefied gas bottles 12 and thus the contents of these bottles 12, which are for example filled with propane, butane, CO2 or similar gas under pressure could be. The devices 11 and II ¹ according to the two exemplary embodiments are very robust, practically maintenance-free and simple in their structural design.

The device 11 according to Figures 1 and 2 has a circular bottom part 13, which is placed stationary on a pad or the floor, and an upper part 14, which is also is circular and that back and forth or up in the axial direction relative to the bottom part 13 and is movably mounted from. This movable mounting results from an intermediate base part 13 and upper part 14 inserted elastic tube 16, which is connected to an incompressible Liquid is filled.

In the case of Ausführungsbexspiel the bottom part 13 has a ring near the outer circumference

projection 17 on which the hose 16 is also circular and concentric to the longitudinal center axis is hung up. The upper part 11 has a channel 18, which by a after below, i.e. towards the bottom part i3 projecting annular rim 21 and through a concentric further inwardly extending projecting ring 22 is formed for this purpose. Is the upper part 14 on the bottom part 13, both of which have the same diameter, is placed on the Hose 16 within the channel 18, the two projecting rings 21 and 22 of the Upper part 13 laterally on the inner or outer circumference of the ring projection 17 at a small distance are arranged so that radial displacement is not possible. The hose is in two approximately concentric turns in the channel 18 or on the annular projection 17 arranged. The inner end of the hose 16 is closed, while the outer end 24 is connected to a manometer or pressure gauge 26, which at one point on the outer circumference of the upper part IH is attached to this.

Upper part 14 put on, as shown in FIG. 1 is indicated, the upper part 14 can move downward under the action of this force move, whereby the hose 16 is compressed and the incompressible contained in the hose 16 Liquid is pressurized. This pressure is passed on to the manometer 26, which shows the prevailing pressure, which, for example, in the case of commercially available standardized liquid gas bottles, directly in the contents can be calibrated. For example, it can be read on the manometer 26 whether the bottle 12 is empty, whether it is a quarter or a quarter half, three quarters or completely full. Such a pressure gauge 26 can be more commercially available Be of construction.

The device 11 'according to the exemplary embodiment of FIGS. 3 and 4 is basically constructed in the same way as far as the function is concerned. This device 11 ', which is also used to determine the contents of a liquid gas bottle, also has a bottom part 13 ' and an upper part 14 ', which are movably connected to one another in the axial direction, wherein the

Bottom part 13 'is arranged stationary. In this embodiment is between Bottom part 13 'and the top part If an elastic Soon 16 'arranged, which is filled with an incompressible liquid and which is connected via a hose 31 to a commercially available manometer 26 ', the in this embodiment also attached to the upper part 14 'and as before described, is calibrated in degrees of filling.

The elastic bellows 16 ', which looks like in round cushions, is arranged in the middle and both in the bottom part 13 'and in the top part 14' in a trough 32, 33, which are formed by annular projections 17 'and 36, the surfaces of which are spaced apart from one another own.

In the circumferential area around the bellows 16 ', in the exemplary embodiment near the outer circumference of the bottom part 13 'and the top part 14' are uniform distributed six compression springs 34 arranged in grooves 18 'and 19' in the upper part 14 'or bottom part 13' are let in at the end.
