G1.6s, g2.5s, G4S(Steel Case) Gas Meters
are type of displacement gas volume meters, which are applicable to meter the
flow rate of combustion gases like natural gas, liquefied petroleum gas (LPG),
marsh gas and coal gas, and their technical performance complies with the
specification of Grade 1.5 in GB/T 6968-2011 Diaphragm Gas Meters.
Independent rotary slide valve, high precision; High quality rubber film and rubber seal are adopted to ensure high sensitivity and reliability. The whole machine is protected by static electricity spraying and has strong anti-corrosion ability. The protective case is connected with a complete stainless steel shell clamping and sealing. Table joints are connected by riveting, with high strength and good sealing.
