The online monitoring system for drainage ends is a system that can monitor the flow rate and water quality of drainage ends in real time and accurately, providing data support for drainage system management, maintenance, and water environment protection..

1. Core Monitoring Components (1) Principle of Doppler Flow Meter: Based on the Doppler effect, particles or bubbles in the fluid will reflect or scatter sound waves that are different from the incident frequency when they move, that is, Doppler frequency shift.

. The Doppler flowmeter emits ultrasonic waves to the fluid, receives ultrasonic signals scattered by suspended particles or bubbles in the fluid, measures the Doppler frequency shift, calculates the fluid velocity, and then combines parameters such as the cross-sectional area of the pipeline to obtain the flow rate value. Installation method: Installed at the bottom of channels or pipelines, the appropriate position should be selected based on factors such as pipeline material, diameter, and fluid characteristics to ensure that the sensor probe is facing the direction of water flow. For example, municipal sewage pipelines can be installed at the bottom center position. Strong adaptability: It can work stably in complex fluid environments containing a large amount of suspended particles, bubbles, impurities, etc. It is suitable for monitoring the flow rate at the end of drainage such as sewage and rainwater, and the measurement results are accurate and reliable. Easy installation: No need for large-scale pipeline renovation or pipeline cutting, Municipal pipeline flow meter

the installation process is simple and fast, and does not affect normal drainage. Real time monitoring: It can continuously measure fluid flow in real time, timely reflect the operation status of the drainage system, and facilitate management personnel to detect abnormalities and take measures. Low power consumption: Some parts adopt low-power design, which can be powered by solar energy, lithium batteries and other methods, suitable for long-term monitoring in the field and places with inconvenient power supply. Application scenarios: Widely used in municipal drainage networks, industrial park drainage systems, urban waterlogging monitoring, and flow monitoring of drainage outlets in rivers and lakes. （2） Common types and monitoring parameters of water quality sensors: pH sensor: monitors the acidity and alkalinity of water bodies, reflects the concentration of hydrogen ions in water, and determines the acidity and alkalinity of water bodies. The measurement range is usually between 0-14pH, and the accuracy can reach ± 0.1pH or higher. For example, in industrial wastewater discharge monitoring, it is possible to promptly detect whether the pH of the wastewater exceeds the standard. Chemical Oxygen Demand (COD) Sensor: It measures the organic content in water through chemical reactions. The higher the COD value, the more organic pollutants there are in the water, which can quickly and accurately monitor the degree of organic pollution in the water. Nitrogen sensor: mainly detects the content of ammonia nitrogen in water. Ammonia nitrogen is one of the important pollutants, and excessive concentration can poison aquatic organisms and lead to eutrophication of water bodies. It can achieve real-time online monitoring of amm
