A flow meter device (1) of the present invention comprises plural fluid passages which are provided between an inlet section (6) into which a fluid flows and an outlet section (7) from which the fluid flows out, and through which the fluid flows; flow value measuring units (M1 to Mn) installed in the plural fluid passages, respectively, and configured to measure flow values of the fluid flowing through the fluid passages; and a control unit (3) configured to determine whether or not to cause one or more of the flow value measuring units to stop a measuring operation of the flow value based on the flow values measured by the flow value measuring units (M1 to Mn), and whether or not to cause the one or more of the flow value measuring units to resume the measuring operation of the flow value, based on the flow value measured by the flow value measuring unit as a monitoring measuring unit which is other than the one or more of the flow value measuring units and is activated to perform the measuring operation of the flow value. |
