Abstract
A wireless opening meter includes measurement portions that measures an opening, a pneumatic pressure supplied to an operation device, and a temperature at an outlet side of the control valve; a failure diagnosis portion that calculates an index of a change leading to a failure of the valve based on a measurement value, and executes failure diagnosis of the valve based on the index; a wireless communication portion that wirelessly transmits the index and a result of the failure diagnosis to a valve maintenance support device; and an adjustment portion that compares the index with a predetermined index determination threshold, and in response to determining that a progression degree towards a failure of the valve is small, perform thinning processing of an operation time of the wireless opening meter by extending an operation cycle of the wireless opening meter to be longer than an initial value.
