Aqueous Ethanol Float Sensor

OPW's Aqueous Ethanol Float Sensor provides industry-leading in-tank detection of water contamination and phase separation. Phase-separated fuel occurs when water in the tank causes the ethanol to become saturated to the point that it can no longer be suspended, and falls out of the gasoline and settles at the bottom of the tank. Fuel contamination resulting from phase separation can cause significant damage to vehicle engines. 

Unlike competing aqueous ethanol detection devices, OPW’s AEF sensor’s real-time density readings are temperature-corrected, which prevents false phase separation alarms. Programmable thresholds allow corrective actions to be deployed before phase separation — and costly inventory losses — occur.
