Level Measurement

Radar Level Measurement

The most effective and precise technique for determining the level of liquid or solid materials in a tank or vessel is radar level type measurement.

There are two kinds of radar level measurements used here:

• Non-contact and contact (guided wave).

Working of a Radar measuring instrument At the top of the tank, an antenna transmits radar signals. The measured surface reflects the signal, and the antenna detects the echo. The frequency of the transmitted signal and the echo differs slightly. The distance to the measured surface determines how much the frequency difference is.

Level Measurement

There are numerous ways to measure a level, and the various kinds of level instruments and transmitters are listed below.

• Radar level

• Capacitive type

• Resistive type

• Ultrasonic type

• Differential Pressure type

• Float type
