The MLR-70 guided wave radar level transmitter measures liquid level inside a tank or sump also suitable for bulk solids and viscous materials with 4-20mA output and LED display.

MLR-70 Guided-Wave Radar Transmitter

The MLR guided-wave radar level sensors are compact level measurement devices that include a transmitter that emits microwave pulses along a rod or wire rope electrode. The pulse propagates along the electrode in the form of electromagnetic wave toward the level surface, where it is reflected and the signal wave component is returned to the receiving module of the electronic housing. The on-board circuitry measures the time of flight of electromagnetic wave and the distance to the surface level is calculated. According to the level height, the level meter output is set and the measured value is shown on the display. Radar level meters are resistant against changes in the atmosphere (pressure, temperature, dust, steam) and to changes in medium parameters (change in dielectric constant and conductivity).
