Overview: Smart water supply metering is an integral part of smart water affairs. In order to promote the development of urban smart water supply metering, many water companies have applied large-caliber ultrasonic water meters to the water supply network in order to achieve comprehensive and dynamic water supply network facilities. Management, real-time monitoring of the operation status of the pipe network, reducing the leakage rate of the pipe network and the difference between production and sales of the water company, etc. This article mainly analyzes the application of large-diameter ultrasonic water meters in smart water affairs from three aspects: technical parameters, product performance, and application scenarios.
1. Technical parameters:
1. Measurement accuracy: level 2;
2. Temperature grade: T50;
3. Environmental grade: Class B;
4. Protection level: IP68;
5. Pressure loss: ≦0.016MPa;
6. Range ratio: R=200 or R=400;
7. The nominal service life of the battery pack: 8 years;
8. Power consumption: Static - 18uA, dynamic (data transmission instant - maximum 400mA).
Product Performance
1. The maximum meter reading frequency is 5 minutes/time;
2. The design of protection grade IP68 can meet the use in a water immersion environment;
3. With GPRS, NB-IoT, CDMA, Lora, and other transmission functions;
4. Supported interface types mainly include M-bus, RS485, TTL, analog, and other interfaces;
5. The supported protocol types are Modbus, and also accept customer-customized internal protocols;
6. The power supply mode includes mains power, solar energy, battery pack power supply, and other power supply modes (choose according to the use environment, and the battery pack is configured by default).
Application scenarios
1. Applied to DMA partition measurement evaluation system and water supply network SCADA system;
2. Real-time monitoring of water pressure, water volume, temperature, and other parameters in the independent metering area of the water supply network;
3. Analyze the changing trend of the minimum flow rate at night, evaluate the leakage of the pipeline network in the area, and provide a basis for real-time alarm analysis of abnormal conditions;
4. Provide data basis for water supply management departments to allocate water resources rationally and make scientific decisions, reduce the work intensity of manual meter reading, and improve the work efficiency of water supply management departments;
5. Provide a basis for monitoring data, water supply scheduling evaluation, abnormal water consumption alarm, pipe network hydraulic model verification, industrial and commercial large user water consumption monitoring and analysis, reducing the production and sales gap of water supply companies, and improving the pipe network management level of water supply enterprises.
Summary: Of course, large-diameter ultrasonic water meters can be applied not only to smart water supply metering but also to other fields. I believe that with the increasing application of ultrasonic water meters, smart water will be getting closer and closer to us.
