Gas meter, PoWoGaz

A bellows-type gas meter is the most popular type of device for measuring the volume of gas flowing through it. It is used in cases where a provider of gas needs to bill an individual user or small enterprise that consumes it. The design of this type of gas meter works as follows: two bellows alternately fill with gas and transfer their reciprocal motion through a servomechanism. This motion is converted to a rotary movement of the drum counter mechanism, which is used for metering the consumption. The limited throughput of the device prevents it from being used for measurements on an industrial scale. The bellows-type gas meter presented here was built by the PoWoGaz company, which had been in operation without interruption since 1925 when it was established as the Water Meter Repair Workshop of the Poznań Water Supply Network.
