1.2 Theory of Operation
The
PanaFlow™ LC
uses a procedure called
Transit-Time Flow Measurement
. In this method, the flowmeter
transmits ultrasonic pulses through a moving liquid. The pulses that travel in the same direction as the fluid
flow (downstream) travel slightly faster than the pulses that travel against the fluid flow (upstream). The
difference in transit times is then used to calculate flow velocity.
