ABSTRACT:
A fluid drip detection system which is not prone to false alarms caused by the presence of dirt or solid particle contaminants in the fluid. The fluid drip detector comprises; a conducting hollow housing for permitting fluid flow and passage therethrough, the housing having a first and second conducting seats. A first conducting door is urged against the first seat and a second conducting door is urged against the second seat. The first and second doors disengage from their respective seats in a drip condition and in response to fluid movement. A conducting rod is connected to one of the doors and is slidingly fitted into a bore in the other door, such that in a no drip condition, if one of the doors is disengaged from its seat by dirt, the other door can still engage its seat, and a lead connected to the housing, for producing an electrical output in the event of a drip. Such electrical output is transmitted to a timer unit that can control the fluid flow by controlling a cut off valve. Such timer can be set both manually, by the user, or remotely, by an electrical signal from the fluid drip detector; where the electrical signal from the fluid drip detector is activated by opening and closing any fluid valve in the system.
