The Multi-jet Series Water Meter LXSG-15E5-20E5 is a high-precision residential water metering device developed and manufactured by Ningbo Zhiyitong Energy Technology Co., Ltd., a professional high-tech enterprise with a 42,600 square meter modern manufacturing center and an annual output of over 1.5 million water meters. Specifically optimized for residential water supply scenarios, this multi-jet water meter adopts an advanced multi-flow channel structure, ensuring stable and accurate metering performance across all flow rate ranges. Compliant with international metering standards, our residential multi-jet water meter is the preferred choice for real estate developers, municipal water utilities, project contractors and bulk building material purchasers, with a proven track record in more than 20 countries and regions across Europe, Africa, the Middle East and Southeast Asia.
The core advantage of the Multi-jet Series Water Meter LXSG-15E5-20E5 lies in its optimized multi-jet metering structure. Unlike single-jet models, this design distributes inlet water flow evenly around the impeller through multiple flow channels, eliminating radial force imbalance and ensuring stable rotation even at extremely low flow rates. This structure delivers consistent accuracy in line with ISO 4064 Class B standards, minimizing metering errors and reducing revenue loss for water supply operators, while ensuring fair billing for end users in diverse residential water use scenarios.
Engineered for long-term reliable operation, this multi-jet residential water meter features a high-quality anti-corrosion brass meter body, wear-resistant engineering plastic movement and fully sealed waterproof structure. With an IP68 protection grade, the meter is fully resistant to dust and water immersion, making it suitable for both indoor and outdoor installation in humid, harsh environments. The optimized structural design reduces mechanical wear, extending the service life of the meter and greatly lowering the long-term maintenance and replacement costs for large-scale residential projects.
The LXSG-15E5-20E5 multi-jet water meter is designed with standardized national and international pipe interfaces, fully compatible with the mainstream DN15 and DN20 residential water supply pipes globally. The compact horizontal installation structure requires no complex on-site modification, enabling fast and efficient installation by construction teams, which significantly shortens project construction cycles. The modular design also simplifies daily maintenance and part replacement, reducing after-sales service input for property management and water utilities.
Specifically optimized for residential water use characteristics, this multi-jet water meter has excellent anti-interference performance, maintaining stable metering accuracy even under frequent water pressure fluctuations. It is fully adaptable to various residential building types, including high-rise apartments, villas, affordable housing and rental communities. With strict quality control throughout the production process, our multi-jet water meter has passed rigorous environmental and performance tests, ensuring reliable operation in diverse climatic and water quality conditions worldwide.
