Working principle of the Doppler flowmeter

When comparing the Doppler flowmeter principle with other principles, it is easy to assume that “Doppler” refers exclusively to the continuous‑wave mode, which can lead to confusion and distortion. Because the pulsed and continuous modes of Doppler flowmeters are fundamentally different, it is always important to specify which Doppler method is being referenced; this will be explained in the present section.

Reasons for Selecting Pipeline Network Flow Monitoring

The pipeline network flow monitoring system primarily involves installing wireless level transmitters and well‑level monitors in urban inspection chambers, enabling real-time transmission of chamber‑level data to the Hengxing IoT’s well‑level monitoring platform. Through this platform, the system supports online analysis of drainage network levels, multi‑tiered alarm notifications, blockage detection, and urban flooding assessment, among other functions.

Functions of the Pipeline Network Flow Monitoring System

Pipeline network flow monitoring provides real-time surveillance of water levels, flow rates, and flow velocities, enabling comprehensive oversight of operational conditions. This system tracks water levels, flow velocities, and flow rates across the entire drainage chain—from discharge points and flood‑prone areas to critical pipeline nodes and outfalls—ensuring a thorough understanding of system performance and supplying data-driven insights for pipeline analysis and operational scheduling.

The Significance of Implementing Flow Monitoring in Ecological River Channels

Radar-based river‑channel flow monitoring consists of a radar current meter, a radar water level gauge, and a flow‑calculation terminal. The radar open‑channel flow‑measurement system is grounded in the theory of uniform flow in hydraulic open channels and employs radar waves to non‑contactly and simultaneously measure both the water level and the surface velocity at a cross section. After computing the surface velocity, the system derives the mean cross‑sectional velocity and then calculates the cross‑sectional discharge and volume using the conventional velocity‑area method. High‑precision radar current meters enable non‑contact velocity measurement, unaffected by sediment or floating debris. They are suitable for flow measurement in typical rivers and channels, particularly under conditions of high flood levels, rapid currents, high sediment loads, and severe pollution.

How is river flow monitored?

River discharge monitoring is generally categorized into natural rivers and artificial channels. Natural rivers are formed by nature, characterized by complex landforms, irregular riverbeds, and the presence of silt, sand, aquatic vegetation, and other materials. When calculating discharge, accurate cross‑sectional surveying is essential, and various factors can significantly influence river flow velocity.

River Flow Monitoring Solution

The channel is manually constructed on-site, with a small cross-section and low sediment content. Therefore, we propose using a Doppler ultrasonic river‑channel flow meter, which can simultaneously measure water level, discharge, and flow velocity. Additional sensors can be integrated to monitor water quality, including routine five‑parameter measurements as well as COD and ammonia nitrogen, enabling real-time water‑quality monitoring within the channel. Live video streaming allows on‑site conditions to be viewed in real time, while a wireless platform provides access to all data—data that can also be analyzed via WeChat or a computer.
