An ultrasonic flow meter is a type of flow meter that uses ultrasound to measure the velocity of a liquid to calculate volume flow.
The Ultrasonic Flow Meter technology is a non-contact means of measuring fluid velocity. They are clamps that attach to the outside of the pipe (and accommodate a variety of pipe sizes) and allow corrosive liquids to be measured without damaging the ultrasonic sensor.
An ultrasonic flow meter (non-intrusive Doppler flow meter) is a volumetric flow meter that requires particles or bubbles in the flow. Ultrasonic meters are ideal for wastewater applications or any dirty liquid that is conductive or water-based. Doppler flow meters generally do not work with distilled or potable water. Vents would be required for clean fluid applications. Ultrasonic flow sensors are also ideal for applications that require low-pressure drop, chemical compatibility, and low maintenance.
The ultrasonic flow meter works by alternately sending and receiving an ultrasonic burst between the two transducers and measuring the time it takes for the sound to travel in either direction between the two transducers.
High Stability - Transit time meters are not affected by the temperature, density, or concentration of the liquids they are measuring, making them a more stable meter. Ability to measure liquids and gases: Ultrasonic flow meters can be used to measure a variety of liquids.
