The OTT RLS (radar level sensor) is a radar sensor for non-contact water level measurements at surface waters.
The sensor uses impulse-radar technology to determine the water level. The RLS is mounted above the water surface e.g.: at bridges or auxilliary constructions. Its solid, relatively light and water-proof housing is easy to install. Its extremely low energy consumption (active: <12mA @12V), the large power supply range and standardized interfaces make the OTT RLS very flexible for different of applications. The RLS covers a measurement range of up to 35m. It is specifically designed for the use in open air locations that have no requirement for mains power supply. The special flat antenna design construction and its minimal energy consumption makes the OTT RLS a economical, practical and reliable alternative to conventional level gauges.

at Rivers with high sediment freight, or weed growth
as redundant senor
at remote sites with no mains power supply
Extremely low power consumption - ideal for remote locations with no mains power supply
Simple mounting - Swivel mount device for easy alignment of the sensor
Uncomplicated system integration - standardized interfaces (4...20mA & SDI-12) for the communication with data loggers
Compact and solid design - long sensor life with minimal maintenance
No stilling well construction needed - sensor is outside of the water
Influence of waves are compensated mathematically - values are compareable to 'stilling well' data
Non-Contact measurement - secure measurements at flood events
