Level Detection for Oil-Water Separators RAC 531

RAC 531 is designed for the monitoring of hydrocarbon fluids separators. With the sensor, OP/10 (OP/5) the alarm device detects when the maximum thickness is reached. The alarm device has a built-in buzzer. A jumper may disable its function; in this configuration, the lighting alarm and relay output inform the current ALARM status to the operator.

The alarm device has an auto-diagnostic of measuring loop and of device integrity. An alarm signal occurs in case of dysfunction. There are three marks on the sensor for easy fitting according to the highest hydrocarbon layer thickness.


  • Survey of an oil-water separator
