Abstract
The invention contemplates an improved magnetically operative flow switch wherein the viscosity sensitivity of a flow-responsive movable metering member is materially reduced, as compared with past constructions. The improvement results from so devising a flow-metering passage through the movable member that such flow is taken only from the center and not from the wall of the inlet-flow passage in which the metering member is movable.
