OTT RLS Radar Water Level Sensor
The OTT RLS, non-contact radar level sensor with pulse radar technology is ideal for monitoring in remote or hard to reach locations.
- Transmit & receive antenna enclosed in a lightweight, durable housing with flat antenna design
- Easily mounts to a bridge, frame, pipeline, or extension arm
- Connects to NexSens X2 data logging system via SDI-12 interface
The RLS non-contact radar level sensor with pulse radar technology is ideal for monitoring in remote areas and applications where conventional measuring systems are not suitable. The RLS accurately and efficiently measures surface water level With a non-contact distance range of up to 115 feet above water. The sensor is IP67 waterproof and has extremely low power consumption, making it ideal for solar-charged monitoring systems.
The radar level sensor uses a revolutionary level measurement technology, meeting the USGS accuracy requirement of +/-0.01 feet. Two antennas are enclosed in a compact housing and transmit pulses toward the water surface. The time delay from transmission to receipt is proportional to the distance between sensor and water surface. A sampling rate of 16 Hz (16 measurements/second) with 20 second averaging minimizes water surface conditions such as waves and turbulence. The RLS does not require calibration and is unaffected by air temperature, humidity, flood events, floating debris, or contaminated water.
