Radar Level Transmitters
A radar level transmitter is a non-contact device that sends a microwave signal from the tank top to the material surface and calculates distance, and so level, from the echo’s travel time. Because it never touches the material it is preferred for aggressive, sticky and hot products.
It is used in liquid tanks, for solids in silos and on open channels, and is largely unaffected by temperature, pressure, vapour and foam. Antenna type, frequency and measuring range are selected for the application.
Main Applications
- Chemical and acid tanks
- Fuel and oil tanks
- Solids in silos and bunkers
- Wastewater and open channels
- Hot and steamy process tanks

Which material? As radar transmitters are not listed in the store, the model is selected per project by tank height, material, internals (agitators, heaters) and connection nozzle. The mounting point should be planned so the signal does not reflect from the tank wall and internals.
