Handheld Ultrasonic Flow Meter Overview

The Handheld Ultrasonic Flow Meter QTFM realizes non-contact measurement of liquid flow, simply install the sensor on the outer wall of the pipeline to complete the flow measurement. The instrument has characteristics of being small-sized, making it convenient carrying and it gives out an accurate measurement.
Handheld Ultrasonic Flowmeter Principle Working: The time-transit measurement principle is adopted, the signal transmitted by one flow meter transducer passes through the pipe wall, the medium, and the other side pipe wall, and is received by another flow meter transducer. At the same time, the second transducer also transmits the signal received by the first transducer. With the influence of the medium flow rate, there is a time difference, and then the flow value Q can be obtained.

Handheld Ultrasonic Flow Meter Applications

This flow meter is widely used in tap water, heating, water conservancy, metallurgy chemical, machinery,  energy, and other industries. It can be used for production monitoring, flow verification, temporary detection, flow inspection, water meter balance debugging, heating network balance debugging,energy-saving monitoring, and it is a necessary tool and meter for timely flow detection.
