Industrial BK-G40, BK-G65, BK-G100

Industrial diaphragm gas meters

Overview
BK-G40, BK-G65 and BK-G100 are compact, light-weight industrial diaphragm gas meters that have been designed to meet the highest demands with respect to measuring accuracy and safety. The innovative new developments are based on the experience of many decades. The gas meters are supplied with screwed cases made of deep-drawn steel sheet as a one-pipe version and – for horizontal and vertical installations – as a two-pipe version.
