GMF508-D 4-20mA pulse large caliber natural gas liquefied gas turbine flow meter
Product Overview
DN350,DN400 large-diameter gas turbine flowmeter is an integrated design of temperature, pressure, flow sensors and intelligent flow totalizers, which is developed by absorbing the advanced technology of domestic and foreign flow instruments to optimize the design and integrating theories of gas mechanics, fluid mechanics, and electromagnetics. A new generation of high-precision, high-reliability gas precision measuring instruments in one, with excellent low-pressure and high-pressure metering performance, multiple signal output methods and low sensitivity to fluid disturbances, widely applicable to natural gas, coal gas, liquefied gas And light hydrocarbon gas measurement.
GMF508-D has been approved by the National Explosion-proof Product Quality Inspection Department according to GB3836.2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", GB38362.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Flameproof Type" d " "And GB3836.4-2000" Electrical Equipment for Explosive Gas Environments Part 4: Intrinsic Safety "i" "passed the standard inspection. The explosion-proof marks are ExdⅡBT6 (flame-proof type) and EiaⅡCT6 (intrinsically safe type). It is suitable for hazardous locations in Zones 1 and 2 of 0 (intrinsically safe type) containing explosive gas mixtures in the temperature groups T1 to T6 of IIA, IIB, and IIC.
