External clamp flowmeter NG800 series

Principle structure

When ultrasonic waves propagate in liquid, the ultrasonic pulses emitted by probe 1 are received by probe 2. At the same time, probe 2 also emits ultrasonic pulses, which are received by probe 1. As a result, the propagation speed of sound waves in the downstream direction increases, while in the upstream direction it decreases. The same propagation distance has different propagation times. By using the relationship between the difference in propagation time and the measured flow rate, the flow rate can be obtained.

Compared with other conventional types of flow meters or other ultrasonic flow meters, the NG800 series not only has the advantages of easy measurement and installation: the sensor can be attached to the outer wall of the pipeline to measure fluid flow, without the need for pipe breakage or diameter requirements, but also has significant features such as high precision, high reliability, and high performance.
