Abstract
A flow control device. The flow control device comprises a valve; an actuator operably connected to and positioning the valve and a controller operably connected to the actuator and providing control signals thereto. An external signal provides control input to the controller. A magnetically actuated sensor is operatively connected to the controller and provides a signal thereto in response to the movement of a magnetic field.
