Claims

[Scope of utility model registration request]

The metal base tube has an outer metal pipe protruding from its lower end into which the liquid to be measured can freely enter, and an annular first tube in which a cuff communicating with the axial hole of the opening is formed on the bottom wall of the metal base tube. A sound wave vibrator is installed inside the base, and the axial metal rod inserted through the axial center hole and the axis of the cuff is coaxially inserted into the outer metal pipe, and the axial metal rod and the metal base are inserted into the outer metal pipe so as to be coaxial. A lower vibration isolating material is filled between the metal base cylinder and the upper part of the metal base cylinder, and a reinforced plastic box frame body is installed in series between the box frame body and the axial metal rod. At the same time as filling the vibration material, the axial center metal rod passing through the openings is supported by upper and lower holes formed in the upper and lower parts of the box frame body, respectively, and A second ultrasonic transducer is fixed to the inner metal rod extending inside the cap made of reinforced plastic, and the first and second ultrasonic transducers are connected to the transmitter/receiver measuring section to form a coaxial ultrasonic liquid.
