OTT RLS - Installation Technical Note

Technical Note for the OTT RLS installation and site selection: The OTT RLS radar level sensor accurately and efficiently measures surface water level.

The OTT RLS sensor technology is based on impulse radar. Two antennas are enclosed in a compact housing and transmit pulses toward the water surface, through a Teflon face plate. The transmitting antenna transmits short radar pulses in the 24 GHz ISM band. The receiving antenna receives the pulses reflected from the water surface to determine the distance between the face plate of the radar sensor and the water surface. The time delay from transmission to receipt is proportional to the distance between sensor and water surface. Approximately T6 individual measurements are conducted per second and averaged after 20 seconds to minimize wave influences.
