Patent ID: 7347255

Claim:
A device for detecting the presence of water in a hydrocarbon pump system for pumping hydrocarbon-based materials from a subterraneous remediation site comprising: a sealed float chamber, said float chamber positioned adjacent to and in fluid connectivity with a hydrocarbon pump, said chamber having an input for receiving hydrocarbon product and an output for discharging hydrocarbon product; a gravity-specific float member slidable along a vertical axis contained within said float chamber, said float having a magnetic element imbedded inside said float member; a sealed switch inside a float guide rod actuated by said magnetic element of said float member coming within close proximity of said sealed switch only when a predetermined amount of water is present in said sealed float chamber, with the hydrocarbon-based material; said predetermined amount of water becomes present in the sealed float chamber when said hydrocarbon pump draws in water present in said subterraneous remediation site in combination with hydrocarbon-based material from said subterraneous remediation site, said actuated sealed switch completes an electrical circuit.
