Described are the method(s) and devices that integrate sensors, algorithms,
software applications, wireless technologies, data protocols, communication
networks, data storage, energy harvesting, computing and processing at the
device, and machine learning techniques to measure valve opening, closing
and intermediate travel statuses based on the position and/or orientation
measurements obtained wirelessly using said devices and peripherals attached
to a handwheel or lever or handle or any other mechanical linkage that is
attached to a valve stem or shaft or plug or disc or any throttling mechanism
inside a valve for the purpose of valve monitoring remotely. The wireless
valve monitoring device can be fitted as a plug-and-play attachment to any
type of valve including, but not limited to, ball, gate, plug, on/off,
butterfly,
globe, pinch, disc, angle, multi-way and any customized valve design with a
stem or shaft or plug or disc which are actuated by a handwheel or lever or
handle or any mechanical linkage. The wireless valve monitoring device can
be used to measure percentage of valve movement in sliding stem, rotary,
quarter turn or multi-turn valves which are actuated by handwheel or lever or
handle driven by manual human intervention or using a pneumatic or electric
or mechanical or electro-hydraulic mechanism. In addition to the valve travel,
the device uses a combination of sensor data and machine learning algorithms
to non-invasively measure, predict and quantify mechanical failures that are
detrimental to valves such as valve cavitation, erosion, flashing, clearance
leakages, hydraulic shocks, hydrodynamic/aerodynamic noise, stiction,
hysteresis, hammering, slamming, leakage through packing-valve
body/bonnet, pipeline induced vibration, and actuator air leakages. Valve
travel, communication status, and valve mechanical health are transmitted
wirelessly from the valve monitoring device over network or relay devices and
gateways to a centralized data processing hub at a remote location and alerts
can be sent to the end-users electronic communication or visualization for
further decision-making, historizing, and automation purposes.
