The Xishuangbanna Branch has successfully completed the application research of the portable ultrasonic flowmeter of Shuichejia
24 Aug,2024
The SCJ-BX01 portable Doppler ultrasonic flowmeter is a device that measures the flow velocity and volume of water bodies by utilizing the Doppler effect of ultrasonic waves. It integrates an ultrasonic transducer, signal processor, pressure and water level gauge, and computing chip internally. By applying professional algorithms, water depth, flow velocity and flow rate data can be calculated quickly and accurately without drift and without calibration. It is also equipped with lithium batteries and TFT LCD screens, featuring a high degree of integration, small size and easy operation. It is widely used in natural rivers, wide and narrow channels, municipal rain and sewage networks, and temporary sewage discharge outlets. In order to accurately analyze the applicable conditions of new instruments, actively promote and apply new instruments and technologies, and enhance the capacity and efficiency of hydrological monitoring, the Xishuangbanna Branch has been earnestly conducting research on the application of domestic portable Doppler ultrasonic flowmeters in the field of hydrological monitoring.
In accordance with the normative requirements and in combination with the suitable environment for portable Doppler ultrasonic flowmeters, the technicians of the branch focused on studying the application of artificial wading in natural river flow measurement. The research adopted a comparative measurement method with the manual wading flowmeter method to observe the relative error or random uncertainty of the flow measured by the portable Doppler ultrasonic flowmeter method in various clear water bodies and complex riverbeds in natural rivers. Through over 30 comparative measurements and analyses at 5 sections of 4 rivers, it is indicated that the equipment has met the requirements of the ultrasonic flowmeter testing specification in terms of error.
On December 26th, the branch organized an internal review and concluded that the domestic portable Doppler ultrasonic flowmeter can be applied to the flow measurement of natural rivers, canalized waterways or channels. After further optimizing the software performance and improving the equipment configuration, it can be used in hydrological patrol surveys, dry water measurement and other flow measurement work. It has significant advantages in measuring the ecological flow of rivers and enhancing the field hydrological survey capabilities.
Next, the Xishuangbanna Branch will closely follow the "14th Five-Year Plan" for scientific research on hydrology in Yunnan Province and the three-year scientific research action plan from 2023 to 2025, actively carry out research on basic hydrological laws and the application of new instruments and technologies, and strive to enhance the modern monitoring capacity and level of hydrology.
