A gas meter device (1) of the present invention comprises plural measurement fluid passages (22a), (22b), (22c) provided in parallel between an inlet into which a fluid flows, and an outlet from which the fluid flows out; flow value measuring sections (61a), (61 b), (61c) provided in the measurement fluid passages (22a), (22b), (22c), respectively, and configured to obtain flow values of fluids flowing through the measurement fluid passages (22a), (22b), (22c), respectively; memories (62a), (62b), (62c) configured to store coefficient data which are values corresponding to the measurement fluid passages (22a), (22b), (22c), respectively and indicating a relation between the flow values of the fluids flowing through the measurement fluid passages (22a), (22b), (22c), respectively, and a total flow value of the fluid flowing from the inlet to the outlet; and total flow value estimation sections (60a), (60b), (60c) configured to estimate total flow values of the fluids based on the flow values obtained by the flow value measuring sections (61 a), (61b), (61c), respectively, and the coefficient data stored in the memories (62a), (62b), (62c). This makes it possible to reduce time required for adjustment work in manufacturing steps of the fluid meter device assembled by connecting the plural measurement fluid passages in parallel. |
