Abstract: A flow rate measurement device includes a turbulence reduction component having opening portions and disposed between a measurement channel and a pair of hole portions across which a pair of ultrasonic transceivers are disposed from the measurement channel. The pair of opening portions of the turbulence reduction component each have frame pieces which are substantially identical in width. This makes it possible to reduce, with small attenuation of ultrasound, the occurrence of turbulence that is attributable to entrained flows in the pair of hole portions and is a cause of measurement error, thereby ensuring measurement accuracy.

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: The physical quantity measurement device includes a secondary flow path disposed outside a multilayer unit and configured to connect an upstream opening to a downstream opening. The secondary flow path is disposed gravitationally below a primary flow path. Ultrasonic transceivers are disposed to project into a flow in the multilayer unit. In the thus-configured physical quantity measurement device, the entry of water droplets into an ultrasonic propagation path and the adhesion of water droplets to the ultrasonic transceivers are substantially prevented, so that, even when the fluid flowing in contains water droplets, the physical quantity measurement device can measure the flow rate of the fluid and the concentration of components contained in the fluid.

Abstract: A physical quantity measurement device is provided which is capable of measuring a component in a fluid to be measured even when the fluid contains droplets such as fine water droplets. The physical quantity measurement device includes, at an inlet opening (5) of a sub-channel (7), an inflow direction regulator (13) which includes guide pieces (12) each of which is inclined at predetermined angle θ with respect to the flow direction in a main channel (1). The angle θ of inflow direction regulator (13) is set to a value that is greater than 90 degrees in relation to the flow direction of the main channel (1).
