ULTRASONIC FLOW METER | Flow Knowledge | KEYENCE America

+

An additional type of flow meter technology uses an ultrasonic sensor. The most popular form of this utilises the principle known as either transit time or time of flight. [Transit time flow meters] Ultrasonic waves are transmitted at an angle across fluid in the pipe. Flow is measured by changes in the transit time for the ultrasonic waves.

FUNDAMENTALS OF ULTRASONIC FLOW METERS

+

Jan 10, 2002· Ultrasonic contrapropagation methods have been used to measure the flow of natural gas since the 1970s, flare gases since the 1980s, and smokestack gases in cem (continuous emissions monitoring) since the 1990s. Contrapropagation means sound waves are timed in a direction with the flow and later or simultaneously, against the flow.

Flow Sensor | Belimo
