integrates temperature, pressure, flow sensors and intelligent flow totalizers developed by itself through
optimized design, integrating gas mechanics, fluid mechanics, electromagnetism and other theories. An integrated
new generation of high-precision, high-reliability gas precision measuring instruments, with excellent low-pressure
and high-pressure measurement performance, multiple signal output methods and low sensitivity to fluid
disturbances,widely used in natural gas, coal-to-gas, liquefied gas , measurement of light hydrocarbon gas and
other gases.
Product Features:

4.The instrument has an explosion-proof function, the explosion-proof mark ExiaIICT6 (intrinsically safe type); the flowmeter case protection class is IP65
