Our compact single-jet water meter LXSG-13D4-25D4 series is a streamlined, high-efficiency flow measurement solution purpose-built for bulk residential construction, modular housing projects, and commercial facility retrofits. Featuring a dry-dial structure, non-magnetic magnetic drive system, and external adjustment design, this ISO 4064 Class B compliant water meter delivers consistent, accurate metering performance while reducing installation and maintenance costs for commercial project contractors, real estate developers, and bulk equipment purchasers. Available in DN13 to DN25 sizes, the meter supports both cold water (≤30°C) and hot water (≤90°C) applications, with a powder-coated brass body that delivers superior corrosion protection in harsh installation environments. Its ultra-compact footprint and lightweight design make it the optimal choice for projects requiring large-scale, standardized meter installation, with flexible length options to fit existing pipeline layouts without extensive modification.
Engineered for high-volume project deployment, this lightweight single-jet dry-dial water meter features a minimized form factor, with DN13 models available in 80 mm and 110 mm length options, and a weight as low as 0.42 kg. The reduced size and weight cut down on transportation, handling, and on-site installation labor costs, significantly improving project efficiency for bulk residential and commercial developments. The standardized connection threads ensure full compatibility with most global pipeline systems, eliminating the need for custom adapters during large-scale rollouts.
Unlike traditional internal adjustment models, the LXSG-13D4-25D4 series is equipped with an innovative outer adjusting device, allowing for on-site calibration and accuracy tuning without disassembling the meter body or interrupting water supply. This design drastically reduces maintenance downtime and operational costs for property management firms and water service providers, with no need for specialized tools or highly trained technicians to perform routine adjustments.
Crafted from high-quality brass with a premium powder coating finish, our powder coated single-jet water meter offers exceptional resistance to corrosion, abrasion, and harsh environmental factors, outperforming standard untreated brass models in humid, underground, or high-moisture installation sites. The non-magnetic structure ensures stable metering performance without interference from common external magnetic sources, maintaining long-term measurement accuracy for reliable billing and consumption tracking.
This magnetic drive single-jet water meter strictly meets ISO 4064 Class B standards, with a precision error control system that delivers ±5% accuracy in the low flow zone (qmin to qt, exclusive boundary) and ±2% accuracy in the high flow zone (qt to qs). With a minimum reading resolution of 0.0001 m³, it captures even minor flow fluctuations, supporting precise water management and leakage detection for large-scale residential and commercial portfolios.
