The offered residential gas meter G6 fully covers the technical characteristics of the RF1 G6 gas meter which we had been successfully distributing on the Bulgarian market for more than 20 years. The meters RF1, created by Schlumberger Rombach in 2001 and later developed by the companies Actaris and Itron, were discontinued in 2021 and Gasterm has found a new partner in the person of the German manufacturer Hermann jr. Pipersberg GmbH.
Pipersberg is a company with over 180 years of company tradition. In 1843, Franz Pipersberg was one of the first in Germany to set up a small production company for gas meters and gradually switched the production from manual to machine work. In order to meet the requirements of the market at the time, the company decided to manufacture water meters in 1885, and with the establishment of two state approved test centers GH/50 for gas meters and WH/50 for water meters, all the meters have been certified in-house since 1972. Today the company produces over 600 000 meters per year at its base in Remscheid, Germany.

The first batch of G6 residential gas meters are already available in our warehouse as we intent to keep permanent stock.
