Ultrasonic flow meters, which are a type of volumetric flow meter, are non-intrusive flow sensors that use acoustic vibrations to measure the flow rate of a liquid. There are two types, Doppler and transit time.
Ultrasonic meters are ideal for automated wastewater applications or any dirty liquid that is conductive or water-based – but will generally not work with distilled or drinking water. These flow meters are also ideal for applications with low-pressure drops, chemical compatibility, and low maintenance requirements.
