Diaphragm Gas Meter Manufacture accord to OIML R31 ( and GB/T 6968-1997 China National Standard for Diaphragm Gas Meter),OIML R31 Certificated. TYPE J, J-I, Size G1.6, G2.5, G4 Domestic Diaphragm Gas Meter, Slant-theft Proof, fraud protection. Applicable scope: natural gas, coal gas, liquefied petroleum gas, mine gas, marsh gas and other artificial burning gases. Technical Parameter: 1)Maximum flow-rate:2.5m3/h4m3/h6m3/h2)Minimum flow-rate:0.016M3/h0.025m3/h0.040m3/h3)Permissible error:Qmin<=Q<0.1Qmax ±3; 0.1Qmax<=Q<=Qmax ±1.54))Maximum working pressure:50kpa5)Total pressure lossa:<=200Pa6)Useable temperature:-10 50°c7)Storage temperature:-20 +60°c8)Center to center distance:110mm or 130mm or customer required.9)Weight:2.4/2.2 Kg The characteristics: 1 Immune gas company from economic loss which is caused by illegal theft through sltant the meter; 2 Air and Water back flow protection, 2Good discharge cruve; 3Low pressure lost; 4The diaphragm is made of Polyester fabric coated with nitride synthetic rubber, passed more than 200 million times of Bally test; 5Build-in mechanism. The case is sealed independently, with tight and nice appearance, easy for cleaning; 6Using Hot-print technology on the counter, its has more clear reading and ensure not depigmentated; 7Good structureimmunethe gas meter from contamination, which ensure a long service life upto 10 years; 8Advanced Magnetic drive.Gas flow data is transferred magnetically to the indicating device, which greatly reduces wear of diaphragm and prolong its service life to 2 million times or 10 years.
