ABSTRACT:
An electromagnetic meter including an electrical coil with a ferromagnetic core. Electrical current flowing through the coil is controlled in a predetermined cycle by a switching mechanism. The meter housing has a material outlet and a bracket is pivotally attached to the housing. A gate is attached to the bracket and is movable between a closed position covering the material outlet and an open position spaced from the material outlet. A permanent magnet is also attached to the bracket and positioned at one end of the core offset from its longitudinal axis. When current flows through the coil the magnet is repelled away from the core, and when current flow is stopped the magnet is attracted to the core. Displacement of the magnet responsive to current flow moves the gate between the open and closed positions.
