Guided Wave Radar Level Transmitter:
In this technique, the level measurement is performed using guided wave radars. The microwave signals are directed to the rod probe or a cable. These signals are reflected by the media surface. The TDR probe of the guided wave radar level sensor helps ensure signal continuity and removes obstacles if any. Guided by this probe, the wave signal also remains high, which makes measurement possible in any harsh environment. This technique is usually employed for measuring the levels of bulk solids and liquids. It is also effective for measuring levels of liquids with two separating layers. The following benefits offered by guided wave radar level transmitter makes it a suitable choice for continuous level measurement across mission-critical applications:
- The TDR probe used in the transmitter remains unaffected by external variables such as steam, pressure and temperature fluctuations, dust and noise, moisture, condensation, and so on.
- Guided wave radar level transmitters require minimal or zero maintenance, as they have no moving parts.
- Unlike other continuous level measurement transmitters, guided radar level transmitters need not compensate for any changes in the dielectric strength, density, or conductivity of the fluid.
