In a doppler type ultrasonic flow meter 1 for measuring the volumetric flow of a measurement object fluid 10 using doppler shift of ultrasound, 1 pair of ultrasonic transducers 3a, 3b perform transmission of ultrasound and reception of an ultrasound echo resulting from the ultrasound being reflected. The 1 pair of ultrasonic transducers 3a, 3b are disposed on an extension line of a measurement line ML for performing measurement of doppler shift, symmetrical about the center axis 5 of a pipe 2 with a measurement object fluid 10 flowing through its inside, and on the outside of the pipe 2. A flow profile for the side opposite, with respect to the center axis 5 of the pipe 2, the side on which the respective ultrasonic transducer 3a, 3b is disposed is used for the calculation of the volumetric flow of the measurement object fluid 10.

Provided is a pressure coupling connector which can decrease the number of components for coping with various electric wire diameters, prevent problems due to difference in product kind, and reduce the stock. The pressure coupling connector includes a wire holding block for holding electric wires and a contact block for holding a connection terminal to which the electric wire is coupled with pressure by inserting the wire holding block into the contact block. The connection terminal of the contact block includes a U-shaped blade rising toward an opening surface into which the wire holding block is inserted. The wire holding block includes a wire holding portion in which a holding hole for transmitting the electric wire from the rear side thereof and holding the electric wire is formed and a reception groove for receiving the U-shaped blade of the connection terminal. The U-shaped blade of the connection terminal includes a core pressing blade having a step-shaped slit with two different widths in the vertical direction and a wire holding blade having a step-shaped slit with two different widths in the vertical direction, sequentially from the inside in an electric wire insertion direction. Adapting to the outer shape of an electric wire, the electric wire can be held with a wire holding slit (upper step portion) 53a or a wire holding slit (lower step portion) 53b.
