Abstract:
A flow detector to detect and monitor the flow of fluid through a conduit comprising a first flow detection element selectively moveable between a first position and a second position and a second flow detection element disposed to operatively engage said first flow detection element when in the first position coupled between a power source and a flow detection monitor such that when fluid flows through the conduit, said first flow detection element moves from said first position to said second position to operatively disengage said second flow detection element to activate the flow detection monitor and when fluid ceases to flow in the conduit said first flow detector element returns to said first position to engage said second flow detector element to deactivate said flow detection monitor, said flow detection monitor includes a means to count the number of flow events detected and a logic circuit to compare the total number of flow events detected to a predetermined number of flow events and to generate a signal when the predetermined number of flow events is detected to provide an indication thereof.
