A fluid flow indicator assembly for monitoring the flow of pressurized fluid through a conduit, said assembly comprising a self-contained unit including a housing having a longitudinal through bore extending from a fluid inlet end to a fluid outlet end of said housing;
- said housing containing an electrical indicator circuit comprising a light emitting diode, a first and a second lead wire, each of said lead wires being axially spaced apart and each extending transversely across said longitudinal through bore, a battery power source for illuminating said diode and being, supported within said housing and being connected to said first lead wire, said second lead wire being connected to said diode, and a normally open electrical switch comprising a fluid pressure operated movable contact, said movable contact being axially movable within said bore and arranged to electrically contact said first lead wire responsive to fluid pressure exerted against said movable contact, and electrically conducting biasing means supporting and restraining said movable contact against movement towards said second lead wire extending across said bore.
A method of indicating fluid flow in a conduit containing fluid, said method comprising the steps of:
- providing a housing having a through bore with a fluid inlet at one end and a fluid outlet at the opposite end of said bore:
- providing laterally spaced stationary electrical conducting elements within said bore and a movable contact axially movable within said bore, said movable contact being in electrical connection with electrically conducting biasing means and being arranged to intercept fluid flow within said longitudinal bore, said biasing means being in electrical and mechanical connection with one of said stationary conducting elements arranged to conduct electrical current from one of said stationary conducting elements to the other of said elements to via said movable contact and further being arranged to bias said movable contact in an axial direction away from electrical connection with said other of said elements in the absence of fluid flow effecting closure of said movable contact with the other of said stationary contact elements;
- counter-boring said housing to provide a receptacle for receiving a light-emitting diode arranged to indicate presence of fluid flow in said longitudinal bore, counter-boring said housing to provide a pocket for receiving at least one button cell battery, and providing electrical conducting leads for completing an electrical circuit from said battery to said diode responsive to fluid flow in said longitudinal bore.
