PURPOSE:To monitor and detect a fault easily and speedily and to improve the safety of the operation of a plant by providing an air receiver equipped with a pressure gauge, a remote operating valve, a flowmeter, a monitoring device for its measured value, and a display device. CONSTITUTION:A monitoring device 15 inputs a signal S1 from a pressure gauge 12 and outputs its variation to a display device 17 successively. The monitoring device 15 inputs flow rate signal S2 and outputs the state of supply piping 10 to the display device 17. This device 17 displays equipment 11 according to priority, and also displays the difference in the air supply amount of the supply piping 10 between a normal and a present point. As the pressure drops to a lower limit, an operator isolates the equipment 11 which exerts less influence upon a plant through a remote operating device 16 from said display, and thus reduces the pressure loss in the air receiver 5. When the remote operating device 16 closes a motor-driven valve 13, or when a broken position, etc., is repaired during said period, the pressure in the air receiver 5 recovers. |
