Abstract: A gas flowmeter includes a device body that air-tightly encapsulates a measurement target fluid, an inlet configured to introduce the measurement target fluid into the device body, an outlet configured to exhaust the measurement target fluid from the device body, and a connector that is connected with the outlet. The gas flowmeter further includes a flow rate measuring part of an ultrasonic type that is connected with the connector and calculates a flow rate of the measurement target fluid flowing inside, and a flow path member that is connected with the connector and has a flow path shape identical with that of the flow rate measuring part. The flow rate measuring part and the flow path member are connected with the connector in a vertical direction in such a manner that a side of inflow ports through which the measurement target fluid flows in faces downward.

Abstract: A measurement unit includes a fluid inlet to let a fluid flow in, a fluid outlet to let the fluid flow out, and a single flow path connecting the fluid inlet with the fluid outlet. The measurement unit further includes a plurality of partition boards and a measuring instrument. The plurality of partition boards are disposed along a current of the fluid and between facing side surfaces of the flow path. The plurality of partition boards define M flow path segments (where M is an integer of 2 or greater) between the facing side surfaces. The measuring instrument measures a flow rate of the fluid flowing through N successively adjacent flow path segments (where N is an integer of 1 or greater and less than M).
