摘要： A locking portion is attached on a curved tube portion of a measurement tube, and a hole portion is formed at a distal end of the locking portion in a vertical direction, and a conical depression is provided on an inner wall surface on outside of the hole portion. A coupling ring of a coupling portion engages the hole portion, and a pivot needle, coming into abutment with the conical depression abuts from an inner wall surface of the coupling ring which faces the conical depression. The other end of the coupling ring is elastically attracted toward a fixing portion via an elastic member formed of an extension spring.

摘要： A first magnetic holder is attached to a U-shaped curved tube portion of a synthetic resin made measurement tube, and a magnetomotive body having a magnetic pole surface facing forward is embedded in a distal end of the first magnetic holder. A second magnetic holder is provided on a substrate at a position facing the distal end of the first magnetic holder with a space apart therefrom. The second magnetic holder includes a permanent magnet disposed to face the magnetomotive body in the first magnetic holder with a magnetic pole surface facing toward the first magnetic holder, so that the magnetic pole surface having a magnetic pole opposite to that of the magnetomotive body face each other. The permanent magnet of the second magnetic holder retains the curved tube portion of the measurement tube elastically with a space apart therefrom by attracting the magnetomotive body with a magnetic attraction force.

摘要： A disposable conduit 1 includes piezo-electric elements 2a and 2b and a memory chip 10 in which calibration data specific to the relevant conduit is stored. Before measurement, a non-disposable electrical measuring circuit reads the calibration data out of the memory chip 10 to prepare a calibrating equation or a calibration table. A flow speed of a blood passing through the conduit or a flow rate calculated from the flow speed is corrected in accordance with the calibrating equation or calibration table.

摘要： An ultrasonic flowmeter capable of increasing the amplitude of, and the receiving sensitivity for, an excited signal is provided. The ultrasonic flowmeter according to the present invention includes two or more ultrasonic transducers on a transmission side and two or more ultrasonic transducers on a receiving side, located as being away from each other on an outer surface of a tube having a fluid flowing therein. The two or more ultrasonic transducers located on the transmission side are driven so as to press the tube at substantially the same pressure to increase an amplitude of an ultrasonic wave. The ultrasonic flowmeter according to the present invention includes adjustment members converting an ultrasonic signal into an ultrasonic signal suitable to measurement between the tube and the ultrasonic transducers. The adjustment members each have a curved surface or a groove at a surface thereof contacting the tube.

摘要： A holder is mounted on a U-shaped curved tube portion of a measurement tube formed of a synthetic resin, and wing-shaped strips having a plate shape protrude outward from the holder. Distortion caused by a Coriolis force which depends on a flow rate is generated symmetrically with respect to a center line passing through a distal end of the curved tube portion and parallel to an outbound tube and an inbound tube. Therefore, the outbound tube and the inbound tube are twisted about the center line of the holder, and an amount of distortion is enhanced by the wing-shaped strips under the principle of leverage for detection.
