MMC's Seacology 2000 slop tank logic system consists of one interface detector and one sonic point probe mounted in each slop tank. The point probe is usually installed 6" above the interface detector. The signals between the two units can differentiate between AIR, SLOPS and WATER. This data is relayed to the control box, where lights indicate existing tank conditions.

Seacology 2000 is approved by IMO as a fixed slop tank oil-water interface detection system. The unit is also approved as intrinsically safe for hazardous environments by BASEEFA and Factory Mutual.
