How They Work

Radar sensors emit low-energy, high-frequency electromagnetic impulses, generated by the sensor’s circuitry. For Guided Wave Radar sensors, these electromagnetic waves are propagated along a probe, which is semi-submerged in the substance to be measured. For Free Air Radar sensors, the waves travel through the air, focused by an antenna.

When the electromagnetic waves hit the surface of the substance, part of the impulse energy is reflected back to the sensor, either up the probe or through the air. The circuitry of the sensor then calculates the level based on the time difference between the impulses sent and the impulses reflected.

True Echo™ technology is not affected by pressure, vacuum, temperature, viscosity, foam, or dust. Changes in dielectric constant or material accumulation on the probe or antenna do not affect the level measurement due to the dynamic sensing technology programmed in our True Echo™ level transmitters.
