Ultrasonic flow meters

Ultrasonic flow meters are flow meters offering a number of advantages over other traditional liquid flow measuring technologies. The most distinct of these advantages is the non-invasive nature of the ultrasonic measuring technique: fluid flow can be measured by clamping a pair of transducers onto the outside of the pipe without contacting the measured fluid. Today, ultrasonic and electromagnetic fluid flow meter technologies represent over 60% of all liquid flow measurement techniques used in industry.

Fluid velocity is measured by sending an ultrasonic pulse from an upstream transducer to a downstream transducer and back again. The measured difference in the amount of time that each pulse takes to traverse the pipe is directly proportional to the mean fluid velocity. Ultrasonic flowmeters use this measured velocity to calculate the liquid flow rate based on user-entered information about the process application.
