Ultrasonic flow meter principle is based on the use and analysis of ultrasonic waves. Such ultrasound is in the range above 20,000 Hz and can reach up to 1000 MHz. There are several principles of flow rate measurement (it will be described below) but all systems have the same main sensing parts: Signal source Receiver Transducer (controller)

An ultrasonic flowmeter (non-intrusive Doppler flow meters) is a volumetric flow meter which requires particulates or bubbles in the flow.

When traveling in the same direction as a flowing medium, ultrasonic waves move faster than waves traveling against the flow. Ultrasonic flow meters use this principle to accurately measure the volume of many liquids and gases - and also to derive parameters like density and viscosity. Watch the video to learn more!
