How Doppler Flowmeters Work
A Doppler
ultrasonic flow meter operates on the Doppler
shift principle , whereby the transmitted frequency
is altered linearly by being reflected from particles
and bubbles in the fluid. The doppler flow meter
net result is a frequency shift between doppler
transmitter and receiver frequencies that can
be directly related to the flow velocity and the
doppler flow meter can calulate volume if the
pipe internal diameter is known. The doppler meter
can calculate the volumetric flow rate but a minimum
amount of solid particles or air in the line to
achieve measurements. These are called reflectors. |
