Household diaphragm gas meters of the series type RS/2001 were developed with special attention to the latest demands for accuracy of measurement and long-term stability.
The production of measuring unit, which mainly determines these two factors, undergoes continuous quality monitoring.
The meter housing in its standard version is made from hot-dip galvanized sheet steel (HTB). An integral folded seam of the housing components re- places the separate folded ring, whereby further reductions in the tendency to leak are further achieved. And there is aluminium housing available for special deployments.
The meter can be used for gases according to DVGW worksheet G260 I, natural gas, liquid gas- air mixtures as well as other non- aggressive gases.
