What is the maximum diameter of wired water meters?
1. Definition of Water Meter Diameter
The water meter diameter refers to the diameter of the inlet and outlet pipes of the water meter, usually expressed in millimeters (mm). The larger the diameter, the higher the maximum flow rate the water meter can handle. For example:
Common diameters for household water use: 15mm, 20mm
Residential or commercial users: 25mm, 40mm
Large industrial users or municipal main pipes: 50mm, 100mm or even larger
2. Diameter Range of Wired Water Meters
Traditional wired water meters are mostly used for households or small commercial users, with common diameters ranging from 15mm to 50mm. However, with technological advancements and increased demand for large-flow metering, the maximum diameter of wired water meters is constantly increasing.
Currently, large-diameter wired water meters commonly available on the market can reach DN200 (200mm) or even DN300 (300mm), mainly used for:
Production water in industrial parks and factories, main pipe metering in municipal water supply networks, and centralized metering in high-rise building complexes.
Large-diameter water meters usually combine mechanical and electronic metering, transmitting flow data in real time via cables to achieve remote meter reading and automated management. Compared with traditional mechanical water meters, large-diameter wired water meters have greater advantages in accuracy, monitoring, and data analysis.
3. Technical Characteristics of Large-Diameter Wired Water Meters
High Flow Capacity: DN200-DN300 diameter water meters can handle flow rates of several hundred cubic meters per hour, suitable for large-scale water supply.
Accurate Measurement: Utilizing multi-stage gear or turbine designs, supplemented by electronic signal output, ensures accurate remote readings.
Remote Meter Reading: Through wired connections, the water management center can monitor water meter data in real time, avoiding errors from manual meter reading.
Pressure and Corrosion Resistance: Large-diameter water meters are typically designed to withstand high pressure and corrosion, adapting to municipal or industrial water environments.
4. Considerations When Choosing a Diameter
Flow Requirements: Selection must be based on the maximum instantaneous flow and average flow to avoid overloading the water meter or inaccurate measurement.
Pipe Matching: The water meter diameter should match the pipe diameter of the network to reduce pressure loss and installation difficulties.
Installation Environment: Large-diameter water meters are bulky and heavy, requiring consideration of support and pipe reinforcement.
5. Development Trends
With the development of smart water management and IoT technology, wired water meters are gradually replacing traditional mechanical water meters in large-diameter applications:
Supporting remote control and data analysis to optimize water supply scheduling;
Can be linked with leak detection and pipeline pressure monitoring systems;
Developing towards larger diameters and higher accuracy to meet industrial and municipal water needs.
The diameter range of wired water meters has expanded from the traditional 15mm-50mm to large-diameter applications of DN200-DN300, meeting the large-flow metering needs of industrial, commercial, and municipal water supply. When selecting, comprehensive consideration should be given to flow requirements, pipe network matching, and accuracy requirements to ensure the long-term stable operation of the water meter. In the future, wired water meters will develop towards larger diameters and greater intelligence, providing more reliable support for urban water management.
