Description
Overview
GAOTek Liquid Ultrasonic Flow Meter uses the time difference principle of ultrasonic wave propagation in the medium to measure the flow rate. It is mainly used to measure liquid, such as ultra-pure liquid, chemical, raw sewage, reclaimed water, cooling water, river water, plant sewage, etc.
