Abstract
A surge relief valve includes a piston housing and a piston located within the housing for reciprocal motion. The surge relief valve also includes a position sensor to resolve the axial position of the piston relative to the piston housing. The position sensor includes a sensor body coupled to the piston housing and a movable element configured to move linearly relative to the sensor body and configured to move axially with the piston. At a least portion of the sensor body is located within the piston housing.
