Kromschröder Breslau gas meter

Apart from orifice and turbine meters, the bellows-type meter is the most popular type of device used to measure the volume of gas flowing through it in situations where a provider needs to bill an individual receiver for the gas they use. The device was patented in 1815 by Samuel Clegg, who worked in the gas production industry. Gas meters were initially used mainly in industrial facilities that needed gas for production purposes and came to be used in households as different types of domestic gas appliances became widespread. Its name comes from the bellows found inside it. The bellows have a known capacity and as they fill with gas, they allow the amount taken from the network to be measured. The movement of the bellows is transmitted to a counter mechanism through a servomechanism, thereby allowing gas consumption to be measured. Manufacturer: G.
