Gas meter and the old locomotive has the same principle, relying on the pressure of the gas to do work on the outside to push the roller counter counter. Gas charges are calculated by cubic meters. The volume of gas expelled by the membrane in the bellows for each actuation is determined by the area of the membrane and the stroke of the actuation (i.e., the amplitude of the actuation). By designing this volume, you can make the roller counter read in cubic meters, so that the total amount of gas used can be read directly from the roller counter.
