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.

Claims (21)

1. 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.

2. The device for detecting the presence of water in a hydrocarbon pump system as defined by claim 1 wherein the amount of water present in said sealed float chamber to actuate said sealed switch is within the range of 100 milliliters to 2 liters.

3. The device for detecting the presence of water in a hydrocarbon pump system as defined by claim 1 wherein said sealed float chamber is positioned upstream of said hydrocarbon pump.

4. The device for detecting the presence of water in a hydrocarbon pump system as defined by claim 1 wherein said sealed float chamber is positioned downstream of said hydrocarbon pump.

5. The device for detecting the presence of water in a hydrocarbon pump system as defined by claim 1 wherein said electrical circuit when completed, activates an alarm.

6. The device for detecting the presence of water in a hydrocarbon pump system as defined by claim 1 wherein said electrical circuit when completed, shuts off the power supply to said hydrocarbon pump.

7. The device for detecting the presence of water in a hydrocarbon pump system as defined by claim 1 wherein said electrical circuit when completed, activates a “tank full” shut-off switch input on an integrated control system.

8. 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 of 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, said electrical circuit activating at least one device from the list comprising an alarm, a pump shut-off switch, a tank-full indicator, a system controller.

9. 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 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 of 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 breaks an electrical circuit.
