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).
