How Does Ultrasonic Clamp-on Technology Work?
The Science of Ultrasonic Clamp-on Technology
When contact with the measured fluid is not possible, ultrasonic clamp-on flow meters are the equipment of choice.
With this technology, ultrasonic waves transmit upstream and downstream through the pipe wall and liquid flowing in the pipe. By measuring the difference in the travel time and knowing the pipe size, the meter determines the velocity and flow rate.
Transit time ultrasonic flow meters use two transducers, which mount to the outside of the pipe and function as both ultrasonic transmitters and receivers. The flow meters operate by alternately transmitting and receiving a frequency-modulated burst of sound energy between the two transducers.
