VALVE MONITORING DEVICE AND SYSTEM Russian patent published in 2012 - IPC F16K37/00 

FIELD: machine building.

SUBSTANCE: network systems includes the following: many additional valve monitoring devices (VMD) (11). Each monitoring device (11) is attached to ball valve (1) and includes the following: sensor of ball valve state; wireless communication unit of narrow working range for transmission of the state as perceived with the above sensor, and for transmission of the state as perceived together with identification of the above device to one or more readout devices (18) of valve devices (VRD), which are located within the above narrow working range; mechanism for attachment of additional VMD to monitored ball valve in the way, which does not disturb the normal functioning of the valve; one or more readout devices of valve devices (VRD) to receive the transmission of valve state and identification of VMD of the above valve monitoring devices (VMD) and for submission of transmission of the valve state to server (21) via Ethernet (25). There is additional valve monitoring device (VMD) operated from storage battery, which is attached on the outer side to available ball valve to monitor the state of ball valve.

EFFECT: furnishing of ball valve with monitoring device that has low cost.
