The microwave level gauge operates by emitting a high
frequency signal of approximately 24 GHz. into a tank and then measuring
the frequency difference of the return signal that bounces off the
product . A great advantage of the microwave level gauge is that no
mechanical object touches or is inserted into the product. The gauge is
ideal for measuring the level of turbulent, aerated,
solids-laden,viscous, corrosive fluids. It also works well with pastes
and slurries.
The gauge shown has a primary 4–20 ma analog signal.
A cut-away view of a microwave level gauge is shown.
The gauge can accept one RTD
(Resistance Temperature Detector) input signal. The
gauge can be configured to display the level, calculated
volume, or standard volume. A microwave level gauge
with meter.
