Abstract
In an apparatus for measuring the volume of a measuring gas, comprising a measuring bell that is movable upwardly and downwardly under influence of the measuring gas and that is suspended from one end of a flexible cable or the like cooperating with a balance device for the measuring bell, the measuring bell together with a stationary body creating a measuring space into which a measuring conduit for the measuring gas communicates, the balance device is constructed in such a manner that it remains operational in a range of measuring bell accelerations that exceed the gravitational acceleration. The balance device exists of a balance weight or a spring element.

An apparatus for measuring the volume of a gas comprising:
- a stationary body having a circumferential channel for receiving a fluid;
- a measuring bell movable upwardly and downwardly in vertical direction which is suspended into the circumferential channel so that a measuring space is formed between the measuring bell and the stationary body;
- a measuring conduit extending axially through the stationary body wherein the conduit communicates at one end with the measuring space and at the other end with the gas to be measured;
- a flexible cable for suspending the measuring bell into the circumferential channel which is fixed at one end to the top of the measuring bell and at the other end to a fixed point wherein the flexible cable passes over at least two guide rolls before it terminates at the fixed point;
- a free pulley supported by the flexible cable between the at least two guide rolls and the fixed point end of the cable wherein the free pulley sits in a free hanging loop of the cable between the guide rolls and the fixed point;
- and
- a balance weight supported by the free pulley having a weight sufficient to position the circumferential edge of the bell in the circumferential channel of the body but not in contact with the body.

- and
- a tension spring attached at one end to the free pulley and at the other end to a fixed point having a tension sufficient to position the circumferential edge of the bell in the circumferential channel of the body but not in contact with the body.
