Detailed Product Description
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, electromagnetics etc. It has excellent performance under both low and high pressure, variety 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>, GB3836.2-2000< Electrical Apparatus for Explosive Gas Atmospheres--Part 2: explosion-proof d> and GB3836.4-2000 < Electrical Apparatus for Explosive Gas Atmospheres--Part 4: Intrinsically Safe Type i>.The ex-marking is ExdBT6(explosion-proof) and/or ExiaCT6(Intrinsically Safe Type). It is suitable for Zone 0(Intrinsically Safe type only), 1, 2 Hazardous (classified) Locations, Dangerous Gases or Vapors Zone: A, B, C and Temperature Classes: T1~T6.
