Non-intrusive valve activity and status indicator

A method comprising:

• storing, in a memory of an analyzer device, one or more state detection logics corresponding to one or more use cases of a piping system including a pipeline,
• receiving, by the analyzer device, user input to select a use case of the piping system,
• selecting one of the state detection logics corresponding to the selected use case,
• receiving, by the analyzer device, a valve state signal from a valve state sensor corresponding to a valve in the pipeline and a flow signal from an activity detector, wherein the activity detector is located upstream or downstream of the valve,
• identifying, by the analyzer device, a valve state based on the valve state signal from the valve state sensor, and a flow reading based on the flow signal from the activity detector,
• determining, by the analyzer device, a status of the piping system, based on the valve state, the flow reading, and the state detection logic for the selected use case,
• sending, by the analyzer device, interlock instructions to a valve in another pipeline of the piping system based on the determined status, and
• generating, by the analyzer device, an alarm signal based on the determined status.
