Why should I consider radar for level sensing?
Besides radar, common technologies in the level market are; float sensors, hydrostatic sensors and ultrasonic sensors. The largest difference with radar per technology is indicated below. If you would like to know whether radar offers advantages for your application, do not hesitate to contact us. We are happy to help you!
Float vs Radar: Radar has no moving parts and is not in contact with the liquid.
Hydrostatic vs Radar: Radar is not in contact with the liquid, radar is not sensitive to (air) differential pressure and offers a direct distance measurement. A pressure reading must be converted and compensated for the air pressure.
Ultrasonic vs Radar: Radar uses (electro magnetic) radio waves which are not sensitive to air pressure differences, humidity and dirt or buildup. Radar also measures through plastic tank walls, even double-walled.
