Difference between ultrasonic flow meter and radar type flow
meter
That's easy. Radar (radio frequency) energy is not widely
used, if at all, in commercial industrial flow meters.
Commercial ultrasonic flow meters use acoustic energy above
the range of human hearing to measure flow velocity of
liquids and gases. The measurement is inherently a
velocity measurement.
Transit time technology for liquids with no suspended solids
or bubbles, or doppler technology can be used for liquids
with suspended solids or bubbles. In-Line transit time
ultrasonic is accurate enough to be used for custody
transfer. Doppler has limited accuracy.
