Non-contact water level sensor for long term surface water measurements.

The OTT RLS is a non-contact radar level sensor with pulse radar technology. The OTT RLS offers a large measurement range with a small blanking distance and narrow beam width and it easily connects to most dataloggers. The RLS has extremely low power consumption and is ideal for remote or solar powered sites.

Application:  Surface water
Parameters measured: Water level / distance to water
Measurement technology:Non-contact pulse radar
Product highlights:Measures water level or depth to water from a bridge, pier or mounting arm
Measurement range: 0.4 … 35 m
Accuracy: 0.8 … 2 m: ± 10 mm; 2 … 30 m: ± 3 mm; 30 … 35 m: ± 10 mm
Internal data logger:No
Interface:SDI-12, RS-485 (using SDI-12), or 4 ...20 mA

Advantages:
  • No drift over time
  • High Performance–Measurements are unaffected by air temperature, humidity, flood events, floating debris, or contaminated water; reduces the likelihood of missing data and reduces data post processing
  • Low Maintenance–Flat antenna design eliminates nesting areas for insects and periodic maintenance requirement
  • Flexible Integration/Easy Setup–Connects to most data loggers via standard communication interfaces, SDI-12 or 4 ... 20 mA; no need for additional PC software
  • Simple Installation–Light weight compact design facilitates easy mounting on bridges, extension mounting bracket or inside a small protective housing
  • Low Profile Design–Unobtrusive appearance is ideal for urban installation sites or sites prone to vandalism
  • Low Power Consumption–Ideal for remote or solar powered sites; requires only 12 mA when active
