Radar Level Transmitters GRLM-70

Radar Level Sensors

Application range

The GRLM-70 Radar level transmitter is designed for continuous liquid level measurement. A guide or rope is used by the radar level meter to measure the level.

Areas of universal application: containers, silos, etc.
It is suitable for use in tanks and reservoirs. It has the ability to respond to level changes very swiftly and decisively.
It is also used to measure the amount of harsh liquids. It also gives a linear and consistent measurement in conductive or non-conductive tanks/vessels of various shapes. Electrical outputs give current output through HART or RS-485 Modbus/RTU.
It can be used in flammable and explosive conditions because it has an Ex-Proof Certificate.
