Abstract
A position monitoring system is configured for use on control valves and other flow controls. These configurations include a motion sensitive unit, for example, a flexible tube with one end that can move in conjunction with a valve stem on the flow control. The flexible tube may hold synthetic oil. Another end of the tube may couple with a pressure senor. In use, this senor may generate a signal that corresponds with head pressure of the synthetic oil in the tube. Operating hardware on the flow control, for example, processing hardware that is part of a valve positioner or controller, may process the signal from the pressure sensor to identify a operating condition of a valve, for example, a position for a closure member of the valve.
