Clamp On Type Ultrasonic Flow Meter works on the Transit Time or Time of Flight
Principle. The flow meter unit utilizes two transducers that functions as both
Ultrasonic transmitter and receiver. The transducers are either clamped on or inserted
to the outside surface of the closed pipes. The transit time flow meter measures the
time it takes for an ultrasonic signal transmitted from one transducer to cross the
pipe and be received by second transducer. The flow is then measured by comparing
the upstream & downstream time of Ultrasonic signal. With no flow through the pipe
the transit time would be equal in both directions.

Principle Of Operation:
For measuring the Flow of the medium, two ultrasonic pulses are sent through the
medium, one in the flow direction and another in the opposite direction. The transit
time of the two pulses are then measured. The transit time between these two pulses
gives the average flow velocity on the propagation path of the Ultrasonic Signals. This
can be used to obtain the average of flow velocity on the cross section of the pipe,
which is proportional to the volumetric flow.
