Diaphragm Gas Meters
Used in most residential and smaller commercial installations, the diaphragm gas meter can measure even a very small gas flow rate .
A virtually continuous flow of gas is directed by internal gas valves which fill and expel gas. This advanced meter technology means that you can rely on gas meter accuracy for a long time.
Honeywell Elster ,Itron and Metrix meters are available with MID approval .

Diaphragm meters are displacement meters where the flow channels are designed to guarantee optimum flow conditions and a low pressure loss. They are suitable for measuring natural gas and a variety of technical gases at up to 0.5 bar. The approved gas temperature range is -20°C to +50°C. The diaphragm meters BK-G4 up to G100 are available with a pulse output option. This allows to retrofit a low-frequency pulser of the IN-Z61 type.
All of the meters are approved for custody transfer measurement by the German PTB and to EN 1359 by German DVGW.
Domestic Diaphragm Meters BK-G4 to BK-G6
These meters are available in co-axial or two-pipe versions. The measuring unit operates on the principle of pneumatic control. This guarantees low noise, long-term stability and high accuracy and allows the possibility of including mechanical temperature correction.
Commercial Diaphragm Meters, BK-G10 to BK-G25
These compact meters are available in co-axial or two-pipe versions with a pressed steel housing. The measuring unit operates on the principle of pneumatic control. This guarantees low noise, long-term stability and high accuracy.
