Diaphragm meters are displacement flow meters where the flow channels are designed to guarantee optimum flow conditions and a low pressure loss. All of the meters are approved for custody transfer measurement by the German PTB and to EN 1359 by German DVGW. 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-G 1.6 up to G 100 are fitted with a pulse magnet as standard. This allows to retrofit a low-frequency pulser of the IN-Z61 type.
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.
