Our single-jet water meter (Model: LXSG-13D5C-25D5C) is a high-precision, durable flow measurement solution engineered for residential and light commercial water metering applications. Manufactured by a leading Chinese high-tech enterprise with over 1.5 million units annual output, this dry-dial, magnetic-driven water meter complies strictly with ISO 4064 Class B standards, delivering reliable and consistent measurement performance for global commercial buyers, project contractors and water utility operators. Available in diameters from DN13 to DN25 (½” – 1”), this residential single-jet water meter supports both cold water (≤30℃ standard, ≤50℃ for cold water models) and hot water (≤90℃) applications. The meter body is crafted from nickel-plated brass for superior corrosion resistance and long service life, with optional anti-magnetic or non-magnetic configurations to meet diverse project requirements. We support bulk wholesale orders, as well as full OEM/ODM customization to align with your brand and technical specifications.
Our ISO 4064 Class B single jet water meter delivers industry-leading measurement accuracy, with an indicating error of ±2% in the high flow zone (from transitional flow rate qt to overload flow rate qs) and ±5% in the low flow zone (from minimum flow rate qmin to transitional flow rate qt, exclusive boundary). The built-in inner adjusting device ensures long-term stability of measurement precision, even after years of continuous use, reducing calibration and replacement costs for bulk purchasers and project operators.
Crafted from nickel-plated brass, this brass single jet water meter offers exceptional resistance to corrosion, rust and water hammer, making it suitable for diverse water supply environments. The dry-dial structure with magnetic drive eliminates water fogging on the dial, ensuring clear and accurate reading at all times. Users can select between anti-magnetic and non-magnetic configurations, as well as cold or hot water models, to match specific project needs.
With a compact, lightweight design, this anti-magnetic single jet water meter features standard threaded connections for universal compatibility and fast, easy installation. The small footprint makes it ideal for tight installation spaces in residential buildings, while the standardized interface ensures strong interchangeability, reducing labor and material costs for large-scale new construction and retrofitting projects.
