ABSTRACT:
A device for detecting the presence of water in a product-only hydrocarbon pump system particularly used for the removal of subterraneous hydrocarbons from a remediation site through a well. The device comprises a sealed float switch chamber, positioned either upstream or downstream from the hydrocarbon pump, wherein when a threshold amount of water is present in the hydrocarbon product being pumped through the float chamber, a switch is actuated by the float mechanism, electrically signaling an alarm, shutting off the power supply to the pump, or further activating a system controller or log.
