Water level radar sensor RL-15 / RL-35
The RL-15 / RL-35 is a highly accurate measuring device to measure the surface water level without direct contact to the medium.
- 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
The so-called pulse procedure sends a short microwave impulse to the water surface. Afterwards the sensor remains in 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.
