Flow monitoring expert – Doppler Ultrasonic flowmeter
Urban drainage networks are responsible for flood control and drainage, sewage collection and transportation in cities. They carry the life safety of a city. And it cannot do without a stable, accurate and easy-to-use traffic detection device. However, traditional monitoring equipment is often affected by installation environment and medium factors, resulting in inaccurate measurements or high maintenance costs, which causes great headaches for many enterprises and maintenance personnel. To address these issues, Aister Doppler ultrasonic flowmeters have developed a “monitoring assistant” that is easy to install, highly accurate, low-power, and maintenance-free – the Doppler ultrasonic flowmeter.

For complex media containing impurities, bubbles and suspended particles, such as drainage networks, industrial wastewater and natural rivers, traditional flowmeters are prone to clogging and wear, resulting in distorted measurement data. Moreover, frequent disassembly and maintenance not only consume a lot of time and effort, but also affect the production progress. The Aister Doppler ultrasonic flowmeter has an IP68 waterproof rating, ensuring the reliability of underwater operation. It integrates an internal pressure water level gauge to achieve integrated monitoring of water level, flow rate and water temperature. It is combined with a remote terminal to calculate the flow rate, enabling remote data transmission. Meanwhile, a free platform is provided for data viewing.
In the face of complex installation environments, whether it is a regular section or an irregular section, by setting the section calculation of the telemetry terminal, data can be stably uploaded (by default, data is collected once every 5 minutes). When the water level, flow rate or flow rate enters the warning range, the wireless transmission module RTU will increase the frequency of data upload and promptly alert the user, playing a role in alarm and early prevention. When not in operation, the monitoring equipment in the radar flow monitoring station is in a dormant state, which can meet the demand for long-term operation.
The Doppler ultrasonic flowmeter also performs well in terms of power consumption. It features a standard RS485 interface and has a long communication distance. Ultra-low power consumption enables normal operation even in remote areas or scenarios without external power supply, truly achieving energy conservation and high efficiency.
From the perspective of application scenarios, Doppler ultrasonic flowmeters are widely used. In the field of municipal environmental protection, they can be used for flow monitoring in urban drainage networks. In the field of agricultural water conservancy, it can be used for flow monitoring of irrigation channels and the inlet and outlet of reservoirs, facilitating the rational allocation and economical utilization of water resources. In addition, it can also be used for scientific research, providing strong data support for the scientific cause.
Choosing a high-quality Doppler ultrasonic flowmeter can not only solve the problem of difficult flow measurement, but also help enterprises reduce maintenance costs and improve management efficiency. At present, the flow measurement equipment on the market is of mixed quality. To choose a brand with strong technological research and development capabilities and perfect after-sales service, one needs to carefully distinguish. Aister offers customized solutions. Based on the specific needs of users such as installation environment and budget, it recommends suitable product models and provides professional installation guidance and technical support.
Today, with the continuous innovation of flow monitoring technology, Doppler ultrasonic flowmeters have broken through the competition with their accuracy, high efficiency and easy installation. Whether you need to solve the problem of sewage discharge monitoring or want to enhance the intelligent management of agricultural irrigation. Doppler ultrasonic flowmeters offer you a worry-free and reliable solution, injecting a continuous force into hydrology and water conservancy.
