Abstract
Disclosed is a non-position sensitive, non-memory condition sensitive, automatic reset flow sensor having a solid housing having an inlet port and an outlet port connected by an axial bore through the center of the sensor housing. An armature is free to move axially within the bore within a range of motion defined by two pairs of detents, the detents extending radially toward the center axis of the bore. The magnetic axis of the compensating magnet is such as to normally oppose the magnetic axis of the armature and, thereby, to apply a magnetic repulsion against the armature to bias the armature toward the inlet port of the sensor housing. The force of magnetic repulsion between the compensating magnet and the armature is, at all times, greater than the force of gravity to, thusly insure that the repulsive force of the compensating magnet will be capable of returning the armature to its original position proximal to the inlet port detents, after the flow condition causing movement of the armature toward the outlet port detents has abated.
