Abstract
A bidirectional flow switch includes a housing having a flow passage therethrough. A body is disposed movably in the flow passage and biased towards a first position at zero flow. A magnetic sensor is disposed proximate the housing. A magnet is disposed with respect to the body and the magnetic sensor so that when the body is at the first position, the magnetic sensor is at a first state and so that the magnetic sensor is at a second state when a flow rate through the flow passage is greater than a threshold flow rate that moves the body from the first position.
