MUF series ultrasonic Flow Meter adopts a state-of-the-art Single-board technology featuring high precision, high reliability, high performance, low price, etc. that make it the ultrasonic flow meter of choice by many customers from all over the world.

When an ultrasonic wave travels in a liquid, the flow of the liquid will cause its speed to change. When it travels in the flow direction, its speed increases and against it, decreases. By measuring the difference in travel times between both directions, one can measure the flow speed.

As shown in Chart 1, a pair of sensors is mounted upstream and downstream on the surface of the pipe. The mounting configuration can be 'Z' or 'V'. The time-difference of ultrasonic signals transmitted and received across upstream and downstream are calculated as below...
