In the field of water resource management and measurement, water meters are the key devices for achieving fair trade and effective monitoring. Among them, brass single-flow water meters, with their outstanding performance, reliable accuracy, and long-lasting durability, have become the ideal choice for measuring cold and hot water in pipes with diameters ranging from DN15 to DN25. This article will deeply analyze the features and applications of this water meter.
I. Product Overview and Application Areas
Brass single-flow water meters are designed for precisely measuring the volume of cold or hot water flowing through pipes. Their core applications cover all scenarios where water consumption needs to be separately accounted for, such as residential homes, commercial buildings, and industrial sites, serving as the basic equipment for achieving water conservation management and cost control.
II. Core Technology and Outstanding Features
1.Single-flow stream and dry faceplate design:
Single-flow stream: Water flows from a single direction impacting the impeller, with a simple and reliable structure, low starting flow, and high sensitivity.
Dry faceplate: The counting mechanism is completely sealed in an independent chamber isolated from the water flow, ensuring clear reading without water fog and maintaining long-term visibility.
2.Magnetic coupling transmission and anti-magnetic interference:
Through high-performance magnetic steel for non-contact transmission, complete isolation between the water chamber and the counter is achieved, fundamentally avoiding the wear and water leakage problems caused by traditional mechanical transmission, and significantly extending the service life.
It has the ability to resist external magnetic field interference, and can effectively prevent measurement errors caused by malicious attacks from strong magnets, ensuring the fairness and accuracy of the measurement.
3.Compact, lightweight and long-lasting clarity:
The overall structure is small in size, lightweight, easy to install and occupies little space.
The counter is designed with a free rotation feature, making reading the numbers easy. Its sealing property ensures that the dial numbers remain clearly visible even after long-term use.
4.International standard certification:
The product technical data strictly follows the international standard ISO 4064, ensuring its global universality and reliability in terms of precision, pressure loss, and durability.
III. Working conditions and accuracy guarantee
Medium temperature:
Cold water meter: 0.1℃ ~ 50℃
Hot water meter: 0.1℃ ~ 90℃
Nominal pressure: PN10/16, capable of meeting the pressure requirements of most building water supply systems.
Pressure loss grade: △p63, meaning that the impact on water pressure during operation is very small, helping to maintain a stable water supply pressure in the system.
Maximum allowable error:
Low flow range (Q1 ≤ Q < Q2): ±5%
High flow range (Q2 ≤ Q ≤ Q4): ±2% (cold water meter) / ±3% (hot water meter)
This accuracy standard ensures that the measurement results are highly reliable throughout the entire range from minor drips and leaks to the maximum water consumption.
IV. Standard configuration and optional functions
Standard accessories: To facilitate installation, each water meter is typically provided with 2 connection pieces, 2 connection nuts, and 2 sealing gaskets, enabling immediate use upon opening the box.
Optional features:
Customized length: We can offer products with different body lengths according to the specific requirements of the customer’s pipe interface.
High-quality body: The body material is brass, which has excellent mechanical strength, corrosion resistance and long-term stability.
Check valve function: An internal check valve can be added to the water meter to prevent water backflow and protect the pipeline system.
Signal output: A reed switch pulse signal option is provided to facilitate remote meter reading, data collection and intelligent monitoring.
Summary
The brass single-flow water meter combines precision, durability, interference resistance and ease of reading. It is a classic choice among traditional mechanical water meters and has remained popular over the years. Its sturdy brass body ensures a long service life in complex water quality environments. The advanced magnetic drive technology and international-standard design provide users with reliable measurement assurance. Whether used for new projects or for replacing old meters, it is an efficient, economical and reliable water metering solution.
