Definition

Level measurement that times a microwave signal reflected from the liquid surface and subtracts the distance from a configured reference height.

Unaffected by air temperature, humidity, and most vapor, which is why it holds calibration in a wet well where ultrasonic drifts. Most field problems are mounting position and false echoes rather than the instrument.
