Valve Position Monitor, And Systems And Methods Of Using Same

A valve assembly comprising:

• an isolation valve configured for use in a water transmission system, the isolation valve comprising:
• a valve body;
• a flow metering body that is movable within the valve body about and between a closed position and a fully open position;
• and
• a stem coupled to the flow metering body, wherein rotation of the stem is configured to move the flow metering body between the closed position and the fully open position;
• and
• a valve position monitor that is retrofit to the isolation valve, the valve position monitor comprising:
• a housing that is configured to be received within and non-rotatably coupled to a valve box of the water transmission system;
• a shaft disposed within and rotatable relative to the housing, the shaft having a first end and a second end, wherein the second end comprises a nut configured for engagement of a wrench;
• a square or rectangular receptacle at the first end of the shaft that receives and couples to the stem of the isolation valve;
• a rotation sensor that is configured to detect a position of the valve stem and output a signal corresponding to a rotational position of the valve stem;
• and
• a transmitter in communication with the rotation sensor, wherein the transmitter is configured to wirelessly transmit the rotational position of the valve stem to a remote receiver.

A system comprising:

• a plurality of valves, wherein each valve is an isolation valve configured for use in a water transmission system, each valve comprising:
• a valve body;
• a flow metering body that is movable within the valve body about and between a closed position and a fully open position;
• a stem coupled to the flow metering body, wherein rotation of the stem is configured to move the flow metering body between the closed position and the fully open position;
• and
• a plurality of valve position monitors, wherein each valve position monitor of the plurality of valve position monitors is retrofit to a respective valve of the plurality of valves, wherein each valve position monitor comprises:
• a housing that is configured to be received within and non-rotatably coupled to a valve box of the water transmission system;
• a shaft disposed within and rotatable relative to the housing, the shaft having a first end and a second end, wherein the second end comprises a nut configured for engagement of a wrench;
• a square or rectangular receptacle at the first end of the shaft that receives and couples to the stem of the respective valve;
• a rotation sensor that is configured to detect a position of the valve stem and output a signal corresponding to a rotational position of the valve stem;
• and
• a transmitter in communication with the rotation sensor, wherein the transmitter is configured to wirelessly transmit a signal corresponding to the rotational position of the valve stem;
• a display device;
• and
• a computing device in communication with the transmitter of each valve of the plurality of valves and the display device, wherein the computing device comprises at least one processor and a memory, wherein the memory comprises instructions that, when executed by the at least one processor, cause the at least one processor to:
• receive the signal corresponding to the rotational position of the valve stem from a valve of the plurality of valves, and
• display, on the display device, a value corresponding to a relative position of the valve.
