Description

Technical Field

[0001] This utility model relates to the field of ultrasonic technology, and in particular to an ultrasonic flow meter. Background Technology

[0002] An ultrasonic transducer is a device that converts electrical signals into mechanical vibrations (sound waves) and vice versa. Its core function is to convert electrical energy into high-frequency ultrasonic signals, or to convert received ultrasonic signals into electrical signals. Ultrasonic flow meters utilize the propagation characteristics of ultrasonic waves emitted by this transducer in fluids, calculating fluid flow rate by measuring changes in the sound wave's propagation time or Doppler frequency shift. Compared to traditional mechanical flow meters, ultrasonic flow meters offer advantages such as non-contact operation, no pressure loss, high accuracy, and low maintenance costs, and are widely used for flow measurement of various fluids, including water, oil, and chemicals.

[0003] In the existing technology, the installation structure of the device is relatively simple and usually lacks a precise sealing structure, making it difficult to ensure a tight fit between the various connection parts. This results in an unsatisfactory sealing effect, which may cause media leakage, gas or liquid seepage into sensitive components, thereby affecting the stability and accuracy of the sensor or detection element, reducing the overall detection accuracy and reliability, and increasing the frequency and cost of maintenance and calibration.

Specifically, the mounting groove 202 provided on the left side of the fixing plate 201 can provide precise limiting space for the sealing strip 203, so that the sealing strip 203 can tightly fit the contact surface between the mounting tube 1 and the transducer body 5, thereby effectively preventing gas or liquid leakage and thus affecting the internal metering effect of the mounting tube 1.

[0021] Reference Figure 1 Four sets of positioning plates 3 are provided on the outside of the installation tube 1, and positioning bolts 4 are inserted into the surface of each of the four sets of positioning plates 3.

The upper surface of the positioning plate 7 has a handle 9, and the outer sides of the two sets of installation strips 8 are equipped with sealing plates 10. Specifically, the cooperation between the mounting strip 8 and the slot enables the transducer body 5 to achieve precise positioning and stable installation, avoiding shaking or displacement during operation. The handle 9 can easily pull the positioning plate 7 and the transducer body 5 out of the mounting tube 1. The sealing plates 10 set on the outer side of the two sets of mounting strips 8 can further enhance the sealing effect during installation, ensuring stable transmission of ultrasonic signals, thereby improving the measurement accuracy and overall reliability of the flow meter.

[0023] Reference Figure 2 A sealing ring 14 is provided on the lower surface of the positioning plate 7, and a matching sealing groove is provided on the upper surface of the mounting tube 1.
