- For oil, petrol and grease separators
- Layer thickness/overflow alarm
- With EX approval for zone 0
Oil, grease and petrol pose a great hazard to groundwater and waste water. WGA 02 monitors the thickness of the layer of separated liquid in oil, petrol and grease separators and generates an alarm signal when it is time to drain the separator. WGA 03 can additionally detect the maximum level in the separator. This avoids overfilling that may be caused by clogged outlets or other circumstances. The unit keeps harmful substances from reaching the sewage water system.
