## Abstract

Systems and methods described herein provide for detection and monitoring a status of a piping system. A valve status detection system includes an activity detector configured to detect flow downstream of a valve in a pipeline of the piping system, and an analyzer assembly. The analyzer assembly stores one or more state detection logics corresponding to one or more use cases of the piping system and receives input to select a use case. The analyzer selects a state detection logic corresponding to the selected use case. The analyzer assembly identifies a flow reading based on a signal from the activity detector and determines a status of the piping system based on the flow reading and the selected state detection logic corresponding to the selected use case.

## Claims

### Claim 1

A system comprising:
an activity detector configured to monitor flow downstream or upstream of a valve in a pipeline of a piping system; and
an analyzer assembly including a processor and a memory configured to:
store one or more state detection logics corresponding to one or more use cases of the piping system,
receive input to select a use case,
select one of the state detection logics corresponding to the selected use case,
identify a flow reading based on a signal from the activity detector,
determine a status of the piping system, based on the flow reading and the selected state detection logic corresponding to the selected use case,
store a life-cycle indicator for the valve, and
monitor received valve state data against the life-cycle indicator.

### Claim 2 (depends on 1)

The system of claim 1, wherein the one or more state detection logics correspond to use cases for an operational mode and a compliance test mode of the piping system.

### Claim 3 (depends on 1)

The system of claim 1, wherein the activity detector is configured to be secured to an outside surface of the pipeline or the valve.

### Claim 4 (depends on 1)

The system of claim 1, wherein the activity detector is configured to non-intrusively collect flow data from the pipeline so as to generate the signal for the analyzer assembly to identify the flow reading.

### Claim 5 (depends on 1)

The system of claim 1, wherein the processor is further configured to process signals from the activity detector as signals for a group including one of gas flow, liquid flow, and mixed gas and liquid flow.

### Claim 6 (depends on 1)

The system of claim 1, wherein, when identifying the flow reading, the processor is further configured to:
obtain a monitoring threshold, of multiple monitoring thresholds, corresponding to a medium in the pipeline,
receive, from the activity detector, a monitoring signal, and
compare the monitoring signal to the monitoring threshold to determine if there is flow of the medium.

### Claim 7 (depends on 6)

The system of claim 6, wherein, when identifying the flow reading, the processor is further configured to perform signal conditioning prior to the comparing.

### Claim 8 (depends on 1)

The system of claim 1, further comprising:
a valve state sensor corresponding to the valve in the pipeline,
wherein the processor is further configured to:
identify a valve state based on a signal from the valve state sensor, and
determine the status of the piping system, based on the valve state, the flow reading, and the state detection logic corresponding to the selected use case.

### Claim 9 (depends on 1)

The system of claim 1, wherein the processor is further configured to:
identify one or more thresholds corresponding to the selected use case.

### Claim 10 (depends on 1)

determine the status of the piping system based on a signal from the auxiliary sensor.

### Claim 15

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.
