Title:
ULTRASONIC LIQUID FLOW RATE DETECTION SENSOR
Document Type and Number:
Japanese Patent JP3841599
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ultrasonic liquid flow rate detection sensor that can be installed without cutting existing piping, and at the same time, can make a span larger, and can easily carry out the alignment between ultrasonic vibrations.
SOLUTION: In the ultrasonic liquid flow rate detection sensor that is arranged opposite to the front and back or piping being formed of a fluororesin, transmits and receives an ultrasonic wave, and detects the flow rate of fluid flowing inside the piping according to the time difference, a rectangular parallelepiped-shaped recessed part 23b with a quadrilateral-shape section is formed in the longitudinal direction of a back surface, at the same time, an engagement part 23c projection in an outer direction is provided at a part other than the recessed part, a sensor holder 23 with a gear-lock part consisting of the recessed part with the same shape as the engagement part is provided, and a shoe 21 is fitted to one part of the recessed part with the quadrilateral- shaped section of a sensor holder, a where the shoe 21 is formed by the same fluorine plastic as the piping, and forms a part in contact with the piping on the same curved surface as the outer periphery of the piping.
