ABSTRACT:
A continuous weighing mechanism, which contains a fluid receiver mounted upon a rocker shaft, said receiver and a portion of said rocker shaft contained within a housing which is supported by a frame, and a fluid flow indicating device, for use with a conduit system wherein a fluid material is moved and is weighed by said mechanism, said device comprising (a) a magnet which is adapted to be detachably connected to said rocker shaft on that portion thereof which is outside said housing; (b) an electromechanical switch which is adapted to be mounted on said frame, said switch being in electromagnetic relationship with said magnet so that movement of said magnet can activate said switch; (c) a control module containing input and output circuits, disposed remotely from said switch and interconnected therewith by suitable electrically conductive means, said control module adapted to receive a signal from said switch through said input circuit and upon preset circuitry conditions, activate an outside electrical power supply through the said output circuit.
