BK Series Diaphragm Meters

BK-Series diaphragm meters 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 barg. The diaphragm meters BK-G 1.6, BK-G 10 up to G 100 are fitted with a pulse magnet as standard. This allows retrofit of a low-frequency pulser of the IN-Z61 type.
