    Abstract: PROBLEM TO BE SOLVED: To provide a flow control valve facilitating maintenance and control. SOLUTION: The flow control valve is provided with a main control valve 70 provided in a line from an inlet 13 to an outlet 16; a flow meter unit 81 outputting a pulse signal substituted for the presence or absence of wash water flow from the inlet 13 to the outlet 16; a flow rate computing circuit for computing the flow rate of a fluid discharged via the outlet 16, based on an electric signal acquired in the flow meter unit 81; a control device 100 for controlling the opening/closing operation of the main control valve 70 based on whether the flow rate computed by the flow rate computing circuit reaches a discharge stop flow rate to stop discharge; and an output part 100a for outputting the flow rate computed by the flow rate computing circuit, to the outside of the control device 100.

    Abstract: An object of the invention is to provide a flow control device having a power saving effect in addition to a water saving effect. Further, another object is to provide a flow control device easy to install, maintain and manage. The flow control device of the invention comprises a flush valve device (1) having a main control valve (70) in a path leading from an inlet (13) to an outlet (16), a flowmeter unit (81) for converting the presence or absence of flow of washing water leading from the inlet (13) to the outlet (16) into a pulse signal and outputting the latter, a control device (100) for controlling the opening and closing of the main control valve (70) according to the output of the flowmeter unit (81), and a power generating unit (205) for generating power by using the flow of the washing water as power, wherein at least part of the power obtained in the power generating unit (205) is supplied to the control device (100).
