WATER LEVEL RADAR SENSOR RL-15 / RL-35
CONTACT-FREE WATER LEVEL MEASUREMENT
The RL-15 / RL-35 is a highly accurate measuring device to measure the surface water level without direct contact to the medium.
FEATURES AND ADVANTAGES
- Contact-free, maintenance-free system
- Measurement range: 15 m resp. 35 m
- Near blanking zone: 0.5 m
- High accuracy: +/- 2 mm
- Compact design
- Independent of environmental influences (e.g. temperature, wind)
- Easy integration into existing systems
- Vandalism secure design does not attract attention
- Interfaces: 4 to 20 mA, SDI-12 is available as an option
- Hydrology: Monitoring river and stream levels for water management and flood forecasting.
- Environmental Monitoring: Measuring water levels in basins, reservoirs, and ecological systems.
- Industrial Process Control: Level measurement in tanks, sumps, and other industrial vessels.
- Flood Warning Systems: Supplying real-time data for infrastructure protection and hazard alerts.
- OEM Integrations: Embedded in larger monitoring or control systems.
- Water Management: Used throughout water treatment and distribution processes for level tracking.
MEASURING PRINCIPLE
The so-called pulse procedure sends a short microwave impulse to the water surface. Afterward, the sensor remains on standby for a short time. Within this time the water reflects the pulses to the integrated evaluation system. The run time of the impulses corresponds directly to the distance to the current surface water level.
