Cut view of Rosemount Microwave Level Guage

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
