The ICON LevelPro ProScan radar level sensor measures the liquid level inside the tank or sump by using a PTFE or SS antenna or horn that sends and receives low-energy radar pulses. The sensor is mounted to the top of the tank and the pulsed signal is reflected off the liquid surface, the echo (returned signal) is then picked up or received by the transmitters antenna. The time it takes is compared to known laws of physics (speed of light), once this is done the distance can be determined, and very accurately measured.
The ProScan series does not contact the process liquid and therefore is an excellent choice for applications that may be corrosive, coating, dirty, or crystallizing. They are temperature-compensated over the entire range (-40-260°F) and can be used on to measure liquid under pressure or vacuum.
The ProScan series is both reliable and accurate; there is no requirement for re-calibration, and virtually zero maintenance as there are no moving parts.
