Elster Gas Meter BKG4

The household membrane gas meter of BK-G4 meets the highest requirements from the point of view of the accuracy of measurement and safety. It unites in itself (himself) innovative technologies and long-term know-how in the sphere of measurement of volume of gas. The BK-G4 counter is delivered in a compound form in options for connection to double-walled ilidvukhnitochny gas pipelines. It is entered in the State register of means of measuring equipment of Ukraine at number U561-09. The movement of membranes is limited to the pneumatic management providing low load of bearings and low noise level during the work. The synthetic membrane is stable by the sizes and has the ellipse form. Use of materials of the superior quality and patented the K-System systems are provided by compliance to the highest quality standards.

The K-System system ideally synchronizes the movement of valves according to supply of gas in measuring chambers. It guarantees excellent linearity even when using small valves. Are approved by the German Federal physics and technology center. Residential diaphragm gas meters G1.6/ G2.5/ G4
