Integrated temperature sensor, pressure sensor, flow sensor and intelligent flow accumulator, the self-developed gas turbine flow meter of LWQ series, which assimilates the advanced technology of flow meters from home and abroad with optimum design, is a new generation of gas flow meter with high precision and reliability based on the theory of pneumatics, hydromechanics, electro-magnetic etc. It has excellent performance under both low and high pressure , various ways of signal output and low sensitivity to the fluid turbulence. thus it is widely applied to the measurement of gas flow, such as natural gas, coal gas, LPG, light hydrocarbon gas and so on.
  The product has been certified by General Administration of Quality Inspection for Explosion-Proof Products according to the GB3836.2000<Electrical Apparatus for Explosive Gas Atmospheres—Part 1:General Requirement>,GB3836.4-2000<Electrical Apparatus for Explosive Gas Atmospheres—Part 4:Intrinsically Safe Type “i”.The ex-marking is ExdⅡBT6(explosion-proof)and/or ExiaⅡCT6(Intrinsically Safe Type).It is suitable for Zone 0(Intrinsically Safe Type only),1,2 Hazardous (classified) Locations, Dangerous Gases or Vapors Zone:ⅡA,ⅡB,ⅡC and Temperature Classes:T1~T6.
Product traits
1.Dedicated instrument to measure gas
2.Oil and gas recovery system
3.High accuracy ,common type +1.5%R,+1.0%R,high accuracy type +0.75%R
4.Good repeatability , reoeatability in a short period of time can reach to 0.05%~0.2% ,it is preferable flow meter in trade settlement because of its high repeatability.
5.Low starting flow ,the first and the only flow meter with low flow velocity and small measuring range in China.
6.Can detect the tamperature ,pressure and flow of measured gas and do automatic tracking compensation to flow.Dispaly cumulative volume of gas in standard condition(Pb=101.325Kpa,Tb=293.15K);do real time query with the data such as temperature ,pressure ,time ,date and etc.
7.Built-in pressure and temperature sensor ,high security ,compact structure and beautiful outlook.
