Application and Solutions of Dayu Electronic Doppler Flowmeter in Water Flow Monitoring at Pumping Stations
In water flow monitoring at pumping stations, selecting the appropriate flowmeter has always been a challenge for engineers and users. Various factors need to be considered, such as pipe diameter, whether the pipe is full, and the on-site environment. Today, we will discuss the application and solutions of the Dayu Electronic Doppler Flowmeter in water flow monitoring at pumping stations.
In pumping stations, monitoring the flow of reclaimed water is particularly important. Reclaimed water is treated wastewater that can be used for irrigation, flushing, and other purposes. However, monitoring reclaimed water flow presents several challenges. First, the pipe diameter in pumping stations is typically large, such as DN1000, which makes installation and measurement difficult for flowmeters. Second, it is necessary to consider whether the pipe is full, as different flowmeters have varying adaptability to full and partial flow conditions. Additionally, the on-site environment can affect the selection and installation of the flowmeter.
The Dayu Electronic Doppler Flowmeter is specifically designed to address these pain points. It adopts a split structure—the sensor and the main unit are installed separately, making it particularly suitable for drainage scenarios. The sensor is responsible for collecting flow velocity, water level, and temperature. The main unit reads data through the RS485 interface and automatically calculates the cross-sectional area and instantaneous flow rate based on channel parameters. It can even synchronously calculate cumulative flow, ensuring data accuracy throughout the entire process.
Environmental adaptability is its strong point. The sensor housing is corrosion-resistant and has an IP68 protection rating, so it can withstand being submerged in sewage. The main unit is IP65 rated, more than sufficient for humid environments. It comes standard with a special cable with an air tube that balances internal and external pressure, extending underwater service life. The cable length can be customized according to on-site requirements. Power supply supports a wide voltage range, and communication is compatible with RS485 and MODBUS protocols, with 4~20mA signal output available. Whether connected to a PLC, data logger, or monitoring platform, it can seamlessly integrate, making remote data viewing and parameter adjustment convenient.
In practical use, the advantages are even more evident: it can measure both partial and full pipe conditions without worrying about pipe diameter; the split design allows flexible sensor installation positions—as long as turbulent flow areas are avoided, accuracy is guaranteed; data is transmitted in real time, allowing the backend to monitor flow changes at any moment; corrosion resistance and high protection mean low maintenance costs in the long run.
The Jiuqu River project in Ziyang, Sichuan, is a typical example—the local authorities used this flowmeter to monitor water level, flow, and gas in the sewage pipe network, providing reliable data support for river ecological protection.
From installation to operation and maintenance, from accuracy to stability, the Dayu Electronic Doppler Flowmeter indeed offers a worry-free solution for water monitoring in pumping stations. If you are troubled by flow monitoring issues, give it a try.
