Diaphragm gas meter

Diaphragm gas meters SGD-1 of standard sizes G 1,6 and G2,5 are designed for assessment of the volume of the consumed natural gas as per GOST 5542-87 or vapours of liquefied carbureted hydrogen gas as per GOST 20448-90, as well as other non-aggressive gases being used in domestic and production purposes.
 
The pulse output device is embedded in gas meters of versions SGD-1I which allows to embed gas meters in the system of automated collection and processing of information.
