General
Bamo NivOil 230 V AC Alarm System for Oil Water SeparatorsDesigned for the monitoring of hydrocarbon fluids separators, the alarm device NIVOIBamo NivOil 230 V ACL may be connected to 1, 2 or 3 sensors.
- Hydrocarbon layer thickness sensor to detect when the maximum thickness is reached.
- Overfill sensor to detect when the fluids are on the highest level; this can occur in case of dysfunction of a filter, when a float-valve closes to prevent an overfilling, when the level of fluid is too high.
- Sludge layer sensor to alarm when maintenance is necessary.
The 3 sensors may be connected to any input of the alarm device NIVOIL. Any combination of the sensors can be wired.The instrument recognizes automatically the sensor type. A LED indicates the sensor type on the diagram on the front board. When an input is not wired, the LED is off.The alarm device NIVOIL has a built-in buzzer; it is possible to disable its function by a DIP switch configuration.
