Dayu Compact Ultrasonic Doppler Flowmeter Enables Intelligent Downstream Discharge Monitoring and Management
Case Study: Qiandao Lake Ecological Downstream Discharge Monitoring in Chun'an County, Hangzhou City, Zhejiang Province
1. Date: November 16, 2025
2. Location: Chun'an County, Hangzhou City, Zhejiang Province
3. Product Used: Ultrasonic Doppler Flowmeter
Project Overview: This project is the Qiandao Lake ecological downstream discharge monitoring project in Chun'an County, Hangzhou City, Zhejiang Province. To achieve intelligent downstream discharge monitoring and management (automatic gate control), ecological water balance control, and advance preparation for summer flood disasters, as well as water diversion management, enabling better and more timely flood control work and management of the ecological water environment balance; real-time water level and flow monitoring of the Qiandao Lake water discharge in the Chun'an County area is implemented, allowing the actual water level, flow velocity, and flow data of the on-site channel to be transmitted to the gate management office computer room. Based on the discharge flow conditions, intelligent control of the gate opening is achieved, enabling more timely response to relevant work.
Product Selection: Based on on-site working condition surveys and the requirements of relevant departments, this project selected the compact ultrasonic Doppler flowmeter manufactured by Fuzhou Dayu Electronic Technology Co., Ltd. to collect real-time data on water level, flow velocity, instantaneous flow, and cumulative flow. The management office's PLC control cabinet collects real-time data via RS485, facilitating the owner's data viewing and effective management on site.
Power Supply: 220V power is available on site, and a 220V-to-12V switching power supply is used to power the ultrasonic Doppler flowmeter.
