[0002] An ultrasonic flowmeter is a device for measuring the flow rate of a fluid. Its principle is that the velocity difference of ultrasonic waves propagating in a stationary medium and a flowing medium is equal to the average flow velocity of the flowing medium. The ultrasonic flowmeter consists of components such as a flowmeter body and two sensors. When the ultrasonic flowmeter is in use, a positioning device is required for fixation. Generally, components such as pipe clamps or iron chains are used to install the two sensors on the pipeline. The two sensors send and receive ultrasonic signals to each other, and the flowmeter body calculates and obtains the flow velocity of the medium. However, the positioning accuracy of traditional positioning devices such as pipe clamps or iron chains is poor, and the two sensors cannot be guaranteed to be aligned with each other, which affects the measurement accuracy to a certain extent and brings inconvenience to users.

The annular nut 411 is used to fix the first C-shaped ring 41 and the second C-shaped ring 42 together. A plurality of limiting grooves 412 are provided at equal angular intervals in a circular array on the outer surface of one side of the third C-shaped ring 48.

At this time, multiple limit slots 412 drive the corresponding cylindrical rods 47 to slide, so that the cylindrical rods 47 and the positioning frames 46 gradually approach the central axis of the pipeline 3 and clamp the pipeline 3. At this time, one of the positioning frames 46 drives the mounting frame 44 and the sensor 2 to be close to the outer wall of the pipeline 3. After installing the two sensors 2, under the action of the hollow tube 418 and the guide rod 419, the two sensors 2 are aligned with each other. After the measurement is completed, rotate the F-shaped locking rod 416 and reverse-rotate the handwheel 415 to loosen the pipeline 3. During the measurement process, if you want to adjust the distance between the two sensors 2, operate the remote control 56 to make the motor two 55 drive the threaded rod 54 to rotate, which can make the two sensors 2 approach or move away from each other.
