product overview

ZEF-GDL204Q gasUltrasonic flow ratecountIt is a new type of flowmeter that works using the principle of time difference measurement.Gas ultrasonic flow meters have gradually entered the field of natural gas metering. Gas ultrasonic flowmeter has high measurement accuracy, no pressure loss, no worn parts, wide range, and can measure both bidirectional and pulsating flow. Compared with other types of flow meters, gas ultrasonic flow meters clearly have more and better performance characteristics. At present, most of the natural gas pipelines constructed in China use gas ultrasonic flow meters for trade measurement.
