- Monitoring of oil/light liquid separators

The NivOil monitoring system is used with oil/light liquid separators. It is used to monitor the level of the accumulating oil/light liquid layer, the maximum accumulation level in case of blockage of the drainage system and, if applicable, the sludge layer settling on the bottom.

Up to a maximum of three monitoring probes can be connected to the sensor power supply unit - type: NivOil CU (BVS 07 ATEX E 090).

The oil probe - type: NivOil OP (BVS 07 ATEX E 091 X) detects the oil/light liquid layer floating on the water.

The high level probe - type: NivOil HP (BVS 07 ATEX E 092 X) detects a blockage of the drainage system.
This alarm can inform that drainage is blocked.

The alternative high level probe - type: NivOil HPS (BVS 09 ATEX E 021 X) detects a blockage of the drainage system. An alarm signal is triggered as soon as the inflowing water has reached a level that is to high.

The sludge level probe - type: NivOil SP (BVS 09 ATEX E 021 X) detects whether a sludge layer has grown on the bottom of the separator.
As soon as the sludge level has reached the too high level an alarm signal is triggered.

All probe inputs are self-configuring.
Therefore, one of the three different intrinsically safe probe types can be connected to each of the three intrinsically safe channels of the power supply unit (NivOil CU). The unit detects which intrinsically safe probe type is connected to which channel and activates the corresponding LED on the front panel.
If a channel is not assigned, its LEDs also remain switched off during operation. The unit has a built-in horn. If necessary, it can be deactivated with DIP switch 1.
