Abstract
An improvement flow sensor of the type having inlet and outlet ports, a moving plate unit for moving in response to fluid flow through the sensor, a sensor unit for sensing the movement of the moving plate and creating a signal related to its location, and biasing unit for biasing the plate towards the inlet (“base elements”). One improvement comprises the moving plate composed of a magnetizable material and the sensor unit comprised of a steel sensor disposed adjacent to a path traveled by the moving plate for sensing the location of the moving plate. Another improvement is to a sensor having, in addition to the base elements, a sealing unit, the improved sealing unit comprising: a bullet rod slidingly received in a bullet port mounted within the sensor and including at a terminal end of the bullet rod a sealing plate adapted to sealingly engage the moving orifice plate, the bullet rod moving in relation to the moving plate until a flared end of the bullet rod engages a bullet port, causing the sealing plate to disengage from the moving plate allowing fluid to pass through the orifice plate. Still another improvement to a sensor having the base elements plus a sealing unit comprises a second sealing unit for preventing flow between an outer periphery of the moving plate and an inner surface of the sensor. A system for using improved sensors in a plumbing system for flow detection and leak prevention.
