1. Discharge outlet flow monitoring

2. What flow meter is good for sewage measurement

Electromagnetic flow meter and ultrasonic flow meter are preferred for sewage in pipelines. The biggest advantage of these two flow meters is that there are no obstructions inside the pipeline. Among them, the technology of using electromagnetic flow meters to measure sewage is relatively mature, but the disadvantage is that when there is sediment in the sewage, wear resistance should be considered; The measurement of ultrasonic flowmeter can be completely carried out outside the pipeline (without modifying the pipeline); Both types of liquid level gauges require the medium to be fully filled in order to measure accurately. For sewage with a large diameter that is often not fully filled, a weir flowmeter can be considered.

The commonly used flow meters for sewage flow monitoring mainly include the following types

1. Electromagnetic flow meters are widely used: widely used in industrial sectors such as petroleum, chemical, metallurgical, textile, papermaking, environmental protection, food, as well as municipal management, water conservancy construction, river dredging and other fields for flow measurement.

. Measurement characteristics: It can only measure conductive liquids, especially suitable for measuring slurries, pulp, slurry, wastewater, and chemical conductive liquids with suspended solids, solid particles, and fibers. Ultrasonic flowmeter technology is developing rapidly: With the advancement of electronic technology, ultrasonic flowmeters are developing rap Flow meter discharge

idly and becoming increasingly perfect, demonstrating their superiority. Application scenarios: It has been widely used in industrial production, commercial metrology, and water conservancy testing. In the measurement of raw water, tap water, reclaimed water, and sewage in the municipal industry, ultrasonic flow meters have a large range ratio and no pressure loss in the Turula section, which improves the measurement accuracy and water delivery efficiency of the official website. In the measurement of industrial cooling circulating water, ultrasonic flow meters have achieved online pressurized installation and online calibration. In summary, electromagnetic flow meters and ultrasonic flow meters are two commonly used flow meters in sewage flow monitoring, each with unique advantages and applicable scenarios.

5. Real time measurement of drainage network flow and water quality

The real-time measurement of drainage network flow and water quality is mainly achieved through the discharge monitoring system, which combines sensor technology, communication modules, and remote management platforms to complete data collection, transmission, warning, and visual analysis.

. The following is the specific implementation method:

1. Real time flow measurement method Sensor selection: Doppler ultrasonic flowmeter (contact type): suitable for full and non full pipe (such as sewage outlets that are mostly non full pipes) scenarios, the flow velocity is calculated by measuring the frequency change of the reflected wave of particles in the water flow, and the flow rate is obtained by combining the pipeline cross-sectional area. The overall height of the equipment is 3cm, and the minimum water level needs to be above 3
