YMQ series gas ultrasonic flowmeter is produced using advanced German technology, and all its key components are imported with original equipment, which has the characteristics of high reliability and long service life. It is a new type of precision measuring instrument with high precision and reliability. It can be widely used for gas flow measurement in industries such as urban gas, petroleum, chemical, power, metallurgy, etc.
YMQ series gas ultrasonic flowmeter adopts a unique multiplexed channels design, which can eliminate the influence of eddy currents and asymmetric flows. The multiplexed channel adds redundant backup channels to improve the reliability of the system. Compliant with Chinese standard GB/T 32201-2015.
