ZT-G4S метр стальной корпус диафрагмы газ 8000 час ан

We are the first manufacturer in China to obtain the five international certificates: OLML R31, EN1359, MID, EEC, NMI, and the first manufacturer in China to pass international new standard. The first manufacturer in the world to pass 8000 hours endurance test when ZT-G4S is tested in NMI Netherland Test Laboratory, and wide measuring range is also verified in NMI laboratory. ZT-G4S steel case diaphragm gas meter with long life and wide measuring range can accurately and precisely measure the flow rate of natural gas meter, liquefied petroleum gas, city pipe gas, marsh gas and so on.
