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 -25 °C to +40 °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.
