AI Technical Summary

Technical Problem

Traditional reflective ultrasonic flowmeters have problems such as bare lines and insufficient stability, especially in humid environments, which can easily lead to unstable connections and measurement errors.

Method used

An ultrasonic flowmeter module is designed, adopting the overall design of the module main body and cover plate, connecting the transducer and control module circuit board through the structure of the cylindrical cylinder and the rectangular frame, and fixing it through glue filling to enhance the sealing and waterproof performance.

Benefits of technology

Through blind hole design and glue filling fixation, the transducer is avoided from contacting directly with gas or liquid in the pipe section, the waterproof performance and stability of the module are improved, the exposed circuit is reduced, and the installation convenience and product integration are achieved.

Abstract

The ultrasonic flowmeter module comprises a module body and a cover plate, the module body is in a cuboid shape, the left end and the right end of the module body are two transducer installation areas respectively, the middle of the module body is a control module circuit board installation area, and the cover plate is arranged on the upper surface of the module body; each transducer mounting area comprises a cylindrical barrel, a closed blind hole is formed in the bottom of the barrel, the upper part of the barrel is closed through a cover plate, a through hole I is formed in the position, corresponding to the transducer, of the cover plate, a plurality of screw holes I are formed in the periphery of the barrel, and the control module circuit board mounting area comprises a cuboid frame body; a cavity is arranged between the frame body and the cover plate, the cavity is communicated with the barrel bodies on the two sides respectively to form an inverted-concave-shaped communicated cavity, the two ends of the control module circuit board extend into the barrel bodies respectively, a second through hole is formed in the upper surface of the cover plate at the corresponding position of the frame body, and a cylindrical terminal groove is formed in an opening of the second through hole. The terminal grooves protrude out of the surface of the cover plate. Through the design of the blind holes, the energy converter is prevented from being in direct contact with gas or liquid in the pipe section, and the waterproof performance of the module is improved. And the transducer is connected with the circuit board through a reasonable structural design, so that the exposure of a circuit is reduced, and the stability of a product is enhanced. And through a process of pouring glue for several times, the integration of the module is enhanced, and the waterproof effect is better.
