Operating Principle of Guided Wave Radar Level Measurement Probes
As already discussed in operating principle of non-contact radar level sensors/gauges, radar level measurement can be done using: guided and unguarded radar waves. We have already covered unguided or non-contacting radar level measurement. Here the focus is on the operating principle of guided wave radar level measurement applications.
Guided wave radar (GWR) is also called time domain reflectometry (TDR) or micro-impulse radar (MIR). In guided wave radar installations, the guided wave radar sensor/gauge is mounted on the top of a tank or chamber, and the probe usually extends to the full depth of the vessel where level measurement is required. A typical guided wave radar installation in a vessel is shown below:
