The OTT RLS is a non-contact radar level sensor with pulse radar technology that is ideal for monitoring in remote or hard to reach locations. The RLS accurately and efficiently measures surface water level by taking approximately 16 individual measurements each second and averaging them after 20 seconds to minimize the influences of waves.
The OTT RLS offers a large measurement range with a small blanking distance and narrow beam width and it easily connects 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.User Benefits:
- Simple setup – no need for additional software, communicates via standard SDI-12 commands
- Versatile – easily mounts to a bridge, frame, pipeline, or extension arm
- Compact – transmitting and receiving antenna enclosed in a light weight durable housing with flat antenna design
- Flexible – connects to most data loggers via standard communication interfaces
- Design – unobtrusive appearance designed specifically for surface water level measurements
- Low maintenance – non-contact measuring principle, no need to enter the water
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
- System integration – supports standardized communication interfaces: SDI-12, 4-20 mA and RS-485
- Low power consumption – Impulse radar technology requires only 12 mA @ 12V
- Installation – mounts to slanted surfaces
- Light weight – weighs less than 5 pounds
