About GMT
GMT GmbH, based in Groß-Gerau, has been developing and manufacturing gas pressure regulators and diaphragm gas meters for controlled pressure regulation and reliable gas measurement in utility networks for over 40 years. The product portfolio comprises low-pressure regulators (PN 0.1, ZRS/HZR and HAR series, DN 25–100) as well as medium-pressure regulators (PN 1/5, MKR series, DN 25–50) and diaphragm gas meters of the BK-G2.5 to BK-G100 series for residential, commercial and industrial applications. The offering is complemented by smart metering components such as encoder registers and communication modules as well as a broad range of accessories with galvanized steel connector pieces, spool pieces, gaskets made of AFM 30 and Nyhalit, gas shut-off valves and pulse transmitters. Services include calibration of gas pressure regulators and diaphragm gas meters, inspection and sample testing, customer seminars, and consulting on installation, commissioning and maintenance. Customers are gas utilities and network operators in Germany. GMT GmbH is part of the Lucerne-based GWF Group with over 125 years of tradition in metrology and control technology.
