Radar Level
Radar level measurement can be used on different liquids, solids, pulps and slurries in tank and vessel level measurement in a wide range of industries and applications. LTH Electronics offer two different types of Radar level measurement;

Pulse Radar

In pulse Radar level, the radar pulses emitted by the antenna are reflected back by the product surface being measured to the antenna with the time gap between the emission and return of the pulse named as the “flight time.” The “flight time is proportional to the product surface distance. A continuous stream of pulses emitted by the antenna provides real time level measurement updated and evaluated many times a second.

Radar level measurement is unaffected by changes to product or process: temperature, pressure, density, conductivity, vapours or dust. Two different frequencies of Radar level transmitters are available, 6GHz and 26GHz.

The RPL Radar level transmitters are available with either a threaded or DIN flanged process connection and either a Rod or Horn antenna depending on the measurement range required. There are seven different models available to cover measurement ranges up to 70 Metres with maximum operating temperatures up to 180°C and pressures up to 40 Bar.

Guided Wave Radar

High frequency pulses transmitted by the Guided Wave Radar level transmitters travel along the surface of a rod or cable suspended from top to bottom of a vessel. When the pulses reach the material surface, they are reflected back up the guide to the sensor. The elapsed time period between transmission and reception of the signal is measured and calculated as a distance and converted to level or volume.

The RWL Guided wave radar level transmitters are suitable for the measurement of bulk solids and liquids in process conditions involving high temperatures, high pressures and low dielectric products for levels up to 30 metres.
