Dayu Electronic Ultrasonic Doppler Flowmeter for Municipal Sewer Flow Monitoring
This project involves a sewer flow monitoring solution designed for a hotel project under a real estate development company in Liaoning Province, aiming to monitor the water flow conditions inside the hotel's sewer pipes in real time and prevent potential risks caused by abnormal water level rises. The system employs advanced Doppler flow measurement technology, providing reliable data support for hotel logistics management.
Project Background and Requirements
The hotel's sewer system has a total length of 100 meters, and flow monitoring equipment needs to be installed at key nodes. Traditional manual inspection methods cannot provide real-time awareness of water flow dynamics inside the pipes, posing the risk of undetected sudden water level increases. To address this, the project team decided to install an intelligent flow monitoring system at the manhole locations, enabling staff to monitor flow changes in the pipes at any time through remote data transmission, promptly conduct on-site inspections when anomalies occur, and effectively prevent pipe blockages or overflow incidents.
Equipment Selection and Technical Solution
After extensive comparison, this project ultimately selected the sewer ultrasonic Doppler flowmeter manufactured by Fuzhou Dayu Electronic Technology Co., Ltd. This device uses non-contact measurement principles, calculating flow velocity and flow rate by detecting changes in ultrasonic frequency reflected by suspended particles or bubbles in the water, making it particularly suitable for municipal sewer environments containing impurities. The equipment is installed at an appropriate position below the manhole opening, with the probe correctly oriented according to the water flow direction to ensure measurement accuracy.
System Functions and Advantages
The monitoring system offers multiple practical functions: First, it uploads real-time data to a cloud server via 4G wireless transmission technology. Second, the accompanying WeChat mini-program provides managers with a convenient data query interface, allowing them to view key parameters such as current flow rate and historical trends anytime, anywhere. Furthermore, the system supports abnormal flow alarm functionality—when sudden flow changes or sustained high levels are detected, relevant personnel are promptly notified to take corrective measures. This intelligent monitoring solution not only improves management efficiency but also significantly reduces the labor intensity and safety risks associated with manual inspections.
Implementation Key Points and Precautions
During project implementation, special emphasis is placed on ensuring that the probe installation is strictly aligned with the water flow direction, as this is a critical factor for measurement accuracy. Additionally, considering the unique characteristics of the sewer environment, the equipment is made of waterproof and corrosion-resistant materials, enabling long-term stable operation in harsh conditions with moisture and corrosive gases. After installation, rigorous on-site calibration and functional testing will be conducted to ensure all performance indicators meet design requirements, providing reliable assurance for the safe operation of the hotel's sewer system.
