The ATWQ series gas turbine flowmeter is a new generation of high-precision and high-reliability gas precision measuring instrument that is developed by incorporating advanced concepts from aviation technology and integrating theories such as fluid mechanics and electromagnetics. It combines temperature, pressure, flow sensors, and intelligent flow accumulators into one device. It exhibits outstanding low-pressure and high-pressure measurement performance, multiple signal output methods, and low sensitivity to fluid disturbances. The ATWQ series gas turbine flowmeter is particularly outstanding in accurately measuring gas accumulation and is considered an excellent commercial trade measuring instrument.
