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.
