ABSTRACT:
A fluid flow sensor for use with a fluid circulating system to indicate a predetermined rate of fluid flow therethrough, fluid flow sensor comprises a hollow fluid flow sensor body including a lower flow detection chamber and an upper fluid flow chamber formed therein and a float movable between a lower and upper position disposed within the hollow fluid flow sensor body, a float position sensing device including logic circuitry to selectively generate a first and second signal disposed adjacent the lower portion of the lower flow detection chamber and a float limit disposed within the upper fluid flow chamber, the float being disposed adjacent the float position sensing device when in the first position when fluid flow through the fluid flow sensor is less than the predetermined rate of fluid flow whereby the float position sensing device generates the first signal to indicate fluid flow of less than the predetermined rate and when the fluid flow through the fluid flow sensor equals or exceeds the predetermined rate of fluid flow through the fluid flow sensor the float moves to the second position to engage the float limit disposed within the upper fluid flow chamber permitting unrestricted flow of fluid through the fluid flow sensor and the float position sensing device generates the second signal to indicate fluid flow equal to or greater than the predetermined rate of fluid flow.
