Good News! | Shui Fa Hangyu Xing's ultrasonic gas meter technology achieves another breakthrough, securing two new utility model patent certifications in a row.

Release date:

2022-04-26

Recently, two practical new patent applications for ultrasonic gas meters, independently developed and submitted by Shui Fa Hangyu Xing IoT Technology Co., Ltd., have successfully received patent authorization certification from the National Intellectual Property Administration.

An ultrasonic gas meter block-type separation and rectification flow channel device (Patent No.: 202121464261.0)

A curved, zigzag-shaped acoustic-path ultrasonic gas meter flow device (Patent No.: 202121464082.7)

Compared to traditional diaphragm gas meters, ultrasonic gas meters offer clear advantages: they boast high accuracy, excellent reliability, and strong real-time performance. Additionally, they excel in terms of compact size, precision, repeatability, as well as longevity, ease of maintenance, and intelligent scalability—making them unmatched in these critical areas. Choosing ultrasonic gas meters is poised to become the dominant trend in the gas-metering industry.

A modular, partitioned rectifying flow channel device for ultrasonic gas meters

The flow channel design of ultrasonic gas meters directly affects the accuracy of their measurement. Typically, without proper flow rectification, these meters exhibit unstable flow velocity distribution, a narrow flow range, significant fluctuations, poor repeatability in measured velocity data, and reduced overall metering precision. Traditionally, installing flow rectifiers involves inserting individual plates into the flow channel one by one—a method that carries certain risks. For instance, if the plates aren’t positioned accurately, making adjustments afterward becomes challenging; and applying excessive force can easily deform the rectifiers, compromising the reliability of the measurement readings. To address these issues, Hangyu Xing has invented a novel block-type segmented flow rectification structure for ultrasonic gas meters. This design allows for precise and easy alignment during assembly, ultimately enhancing the accuracy of ultrasonic detection and improving the precision of indicated error values.

A curved, zigzag-shaped acoustic path ultrasonic gas meter flow device

Currently, none of the verification channels for China's various ultrasonic gas meters under development provide effective flow rectification. As a result, the gas flow velocity remains unstable, with uneven velocity distribution and significant fluctuations, leading to reduced measurement accuracy. In contrast, Hangyu Xing's invention features a uniquely shaped flow channel that transforms the gas flow from its turbulent, erratic state into a stable, streamlined condition. Additionally, the innovative design of the zigzag acoustic path increases the number of times ultrasonic signals pass through the gas flow, enhancing measurement precision and ultimately improving the overall accuracy of ultrasonic gas metering.
