A recently granted patent (Publication Number: US11920465B2) discloses an apparatus designed for detecting and indicating the operational position of a valve. The apparatus includes a sensor that is in contactless communication with a target surface on a moveable part of the valve, allowing it to measure the detected distance along an axis between the sensor and the target surface. This enables the determination of the valve's operational position as the moveable part moves in different directions along the axis. The sensor can be in acoustic or electromagnetic communication with the target surface, providing flexibility in its application.

Furthermore, the patent describes a system that incorporates the aforementioned apparatus along with a processor to receive the output signal from the sensor and generate a display signal indicating the valve's operational position. The system also includes a display unit that can be located remotely from the valve or associated equipment, enhancing accessibility and usability. The method outlined in the patent involves securing the apparatus to the valve or associated equipment, measuring the detected distance, and indicating the operational position of the valve actuator based on this information. By following a series of steps, including processing the output signal and displaying the relevant data, the method ensures accurate and efficient detection and indication of the valve's operational position.
