|
Process data
Measuring task:
Differential pressure and level measurement
Measuring point:
Filter tank
Measuring range up to:
+3 bar
Medium:
Untreated water
Process temperature:
+2 … +15 °C
Process pressure:
0 … +3 bar
Special challenges:
Sand and stone particles in the filter material
Application
The suspended matter is filtered out of the water via the sand and gravel filled filter tank. Pressure is applied to pump water through the filter bed. Dirt particles are retained in the filter material. The electronic differential pressure measurement monitors the level of contamination in the filter. As soon as the threshold contamination is exceeded, an automatic cleaning cycle of the filter is triggered.
