Dinel Hydrostatic Level Meter is a compact measuring device containing a ceramic geometric sensor and evaluation electronics in a stainless steel probe. The ceramic sensor is resistant to lightly soiled, or sludge water. From the probe, the housing comes out 2-wire cable with a capillary (for atmospheric pressure compensation). The front side of the sensor is open, therefore the level meter is resistant to capturing gross (solid) impurities. The level meter has no customer-accessible adjusting elements.
Features
- For continuous level measurement of clean, lightly soiled, or sludge water in non-pressure reservoirs, boreholes, tanks, etc.
- Precise customer choice of the measurement range up to 100 m (H2O)
- The health certificate for contact with potable water is available
- Current or Voltage output
- Easy “plug and play” installation without any settings
