- 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
- 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
- For surface water level measurement of:
+ Streams and rivers
+ Tidal zones
+ Reservoirs and lakes
- Ideal for monitoring:
+ Surface waters prone to flooding
+ Sediment or debris laden streams and rivers
+ Migrating channels
