FLUID FLOW DETECTION DEVICE |
摘要 |
<p>A fluid flow detection device includes a housing of non-magnetic metal, a flow passage through the housing and a valve seat in the flow passage. A magnetic valve element emits a magnetic field. The valve element is movable relative to the valve seat between a closed position blocking fluid flow through the flow passage and an open position allowing fluid flow through the flow passage. The magnetic valve element is biased toward the closed position. A magnetic field enhancer is movable with the magnetic valve element for enhancing the magnetic field. A magnetic field sensor on the housing is operable to signal a change in position of the valve element as it moves between its open and closed positions.</p> |
