ABSTRACT:
A fluid flow sensor includes a housing defining a flow path for fluid flow therethrough. A valve member slidably engages the housing and moves with respect to a fixed cylindrical metering member in response to fluid flow through the flow path. A spring biases the valve member to a no-flow position. A portion of the valve member engages a seat to prevent reverse fluid flow. The metering member receives one end of the valve member while a reluctive displacement transducer is received by a bore extending into the valve member from the other end.
