Fluid measuring device

Japanese Patent JP5914870

B2

A gas meter device of the present invention includes an inlet into which a fluid flows, and an outlet from which the fluid flows out, and is configured to derive a flow value of the fluid flowing from the inlet to the outlet. The gas meter device comprises plural measurement fluid passages provided in parallel between the inlet and the outlet; flow value measuring units (61a) to (61e) provided in the plural measurement fluid passages, respectively, and configured to independently measure flow values of fluids flowing through the measurement fluid passages, respectively; an average flow value calculation unit (92) configured to derive an average flow value of the flow values measured by the flow value measuring units (61a) to (61e), respectively; and a flow value comparison unit (93) configured to obtain index values indicating a relation between the average flow value derived by the average flow value calculation unit (92) and the flow values measured by the flow value measuring units (61a) to (61e), and determine whether or not each of the index values is equal to or larger than a predetermined value. Thereby, the present invention can determine whether or not there is an erroneous measurement flow value from only the separate flow values independently measured in the measurement fluid passages, respectively.
