Ultrasonic Clamp on

Clamp-on ultrasonic flow meters operate on the principle of transit-time or time-of-flight measurement. They work by sending ultrasonic signals through the fluid in a pipe from one transducer to another, and then in the reverse direction. The time it takes for the ultrasonic signals to travel downstream and upstream is measured. When the fluid is flowing, the downstream signal takes less time to traverse the pipe compared to the upstream signal. The difference in time is proportional to the flow velocity of the fluid. By using multiple pairs of transducers and carefully analyzing the time differences, these meters calculate the average velocity of the fluid at different points within the pipe. This information is then used to determine the volumetric flow rate of the fluid.
The "clamp-on" aspect refers to the non-intrusive installation of transducers on the external surface of the pipe, making these flow meters suitable for retrofitting on existing pipelines without disrupting the flow.
