The GRLM radar level meters are compact measuring devices consisting of two main parts – a level meter (housing) and a display module (display). The electronics transmit very short electrical pulses (0.5 ns), which are linked to a one-wire transmission line (measuring electrode). Measuring electrode can be created of rod or rope.

The pulse propagates along the electrode in the form of an electromagnetic wave toward the level surface, where it is partly reflected and the reflected component is returned to the receiving module of the electronics. The electronics measure the time of flight of electromagnetic waves and the instant distance to the surface level is calculated. Then based on the height of the level, the level meter current output 4 .. 20 mA is set with the HART communications or an industrial RS-485 line with Modbus RTU communications, and the measured value is shown on the display.

Radar level meters with guided waves are suited to the continuous level measurement of various liquid, mush, and bulk-solid materials. Level meters are resistant against changes in the atmosphere (pressure, temperature, dust, steam) and to changes in medium parameters (change in dielectric constant, conductivity)
