Contact-free water level measurement
The SOMLEVEL-8 / 15 / 30 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: 8m; 15 m; 35 m
- Near blanking zone: 0.1 m
- High accuracy: +/- 2 mm OR +/- 5 mm (SOMLEVEL-30)
- Compact design
- Independent of environmental influences (e.g. temperature, wind)
- Easy integration into existing systems
- Interfaces: 4 to 20 mA OR SDI-12 OR RS-485 MODBUS
Measuring principle
The so-called frequenzy 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.
