Designed for the monitoring of hydrocarbon fluids separators, the alarm device NivOil 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. 
• Sludge layer sensor for alarming 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.
The alarm device NIVOIL has a built-in buzzer; it is possible to disable its function.

Low power consumption
This model, working with a 10 to 27 V DC power supply, has low energy consumption. It is designed for the use of a solar powered battery or any standard electric battery (consumption is 0.1 W – 12 V DC – with 3 sensors
connected with one complete control cycle per hour).

Sleep mode
This mode is adjustable by modifying the frequency of control cycle (from 6 minutes up to 9 days). A continuous control mode could be switched on when there is no limit on energy consumption.

ATEX certified
All the components are ATEX certified. The sensors are for a location in zone 0 and the alarm device corresponds to a zone 2.
