Mounting the SLU-103-** Sludge Level Sensor
The sensor must be immersed when the liquid is at its normal level (water zero
line).
The exact immersion depth depends on
■
the type of oil/petrol separator,
■
its design
■
and the height of the maximum sludge layer thickness.
The sensor must always be immersed in the liquid. The switching point of the
sensor is located at the same level as the reflectors.
