How does an
ultrasonic clamp-on
flow meter work?
ATTRIBUTES
The measuring principle is based on the ultrasonic transit time method. To measure the flow rate, two ultrasonic sensors (clamp-on sensors) are mounted on the outside of the pipe. The ultrasonic signal of the sensors pass through the pipe and the medium both with and against the flow direction. The calculated difference in the transit time of two opposing signals is directly proportional to the flow velocity and can be displayed as a flow volume with the input of additional pipe parameters.
