The LXH-15AS-20AS series volumetric piston water meters are high-performance flow measurement solutions engineered for residential water supply systems, especially in regions with challenging water quality conditions. Manufactured with premium engineering plastic nylon, these ISO4064 Class C water meters deliver stable, reliable, and highly accurate water consumption tracking, making them the ideal choice for business clients seeking cost-effective, low-maintenance metering products for bulk deployment. Designed in strict accordance with international ISO4064 standards, our piston water meters for bad water areas support DN15 and DN20 specifications, adapting to common residential pipeline configurations, with optional cold and hot water models to meet diverse project requirements. As a trusted manufacturer of residential piston water meters, we offer bulk supply and flexible customization services to match the unique needs of every commercial project.
Crafted from high-grade plastic nylon, these plastic nylon volumetric water meters offer exceptional resistance to rust, scaling, and chemical corrosion, outperforming traditional metal meters in water environments with high sediment or impurity content. This material design drastically extends the meter’s service life, reduces frequent maintenance and replacement costs, and delivers long-term value for project contractors and water utility operators. The lightweight structure also simplifies transportation and on-site installation, cutting down overall project labor costs.
Certified to ISO4064 Class C accuracy standards, our volumetric piston water meters maintain industry-leading measurement stability across all flow ranges. In the high flow zone (from transitional flow to overload flow), the indicating error is controlled within ±2%, while in the low flow zone (from minimum flow to transitional flow), the error is within ±5%. This ultra-high sensitivity ensures accurate metering even at minimal flow rates, effectively reducing non-revenue water for water utility companies and protecting the revenue of commercial purchasers.
The LXH-15AS-20AS residential water meters are available in DN15 and DN20 sizes, with dual optional installation lengths and standard G-thread connections, fully compatible with most existing residential pipeline systems worldwide. The meters support a working pressure of up to 1Mpa, with cold water models suitable for temperatures ≤50℃ and hot water models for temperatures ≤90℃. This wide adaptability makes them suitable for various project types, from new residential construction to old meter retrofitting projects.

Our LXH-15AS-20AS piston water meters are tailored for bulk commercial use across multiple scenarios, including:
Residential real estate development projects, including affordable housing and mass apartment complexes
Municipal and rural water supply systems, especially in areas with poor water quality and high sediment content
Water utility management companies for large-scale meter replacement and retrofitting projects
Apartment and property management companies for daily water consumption monitoring and billing
Temporary water supply projects for construction sites and industrial parks
These volumetric piston water meters are designed and manufactured in full compliance with ISO4064 Class C standards, ensuring consistent measurement performance and quality that meets global regulatory requirements for residential water metering.
Yes. The plastic nylon construction and volumetric piston design make these meters especially suitable for regions with poor water quality, as they are highly resistant to scaling, clogging, and corrosion caused by sediment and impurities in the water.
We offer both cold and hot water models. The standard cold water meter is suitable for water temperatures ≤50℃, while the hot water version can be used for temperatures up to 90℃, meeting the needs of domestic hot water metering projects.
Yes. We offer comprehensive OEM and ODM services for bulk orders from business clients, including customized logo printing, dial design, and packaging solutions, to align with your brand and project requirements.
