OTT RLS Radar Level Sensor

Download Site Selection & Installation Guide

The OTT RLS Radar Level Sensor is a non-contact radar level sensor that is ideal for measuring surface water in remote or hard to reach locations. The RLS accurately and efficiently measures surface water level at an accuracy of ±0.01 ft. Approximately 16 individual measurements are conducted each second and averaged after 20 seconds to minimize the influences of waves.

The RLS offers a large measurement range with a small blanking distance and narrow beam width. The sensor is easily connected to most any data logger via standardized communication interfaces. The RLS has extremely low power consumption and is ideal for remote or solar powered sites.

OTT RLS Features:

Accurate: ±0.01 ft accuracy for water level measurements, and will not drift over time
Fast: water level measurements available every 20 seconds
Performance: unaffected by air temperature, wave action, humidity, flood events, floating debris, or contaminated water
Low power consumption: Impulse radar technology requires only 12 mA @ 12V
Installation: mounts to slanted surfaces
Light weight: weighs less than 5 pounds
