Our wet dial magnetic woltman water meters (Model LXL-80-200) are heavy-duty, large-flow industrial metering solutions designed for high-volume water consumption measurement in municipal, industrial, and large-scale commercial applications. Produced by Ningbo Zhiyitong Energy, a trusted manufacturer of industrial metering equipment, these horizontal woltmann meters feature a wet dial with magnetic transmission, a sealed direct-reading number roll mechanism, and a corrosion-resistant brass ring, delivering stable and accurate performance in continuous high-flow operating conditions.
Available in diameters from DN80 to DN200 (3” – 8”), these meters support both cold water (≤30°C) and hot water (≤90°C) applications, with a removable measuring insert for simplified maintenance. Pre-equipped for impulse emitter device installation (even after initial on-site setup), these large flow industrial water meters offer flexible retrofit options to adapt to evolving smart water management needs, making them the ideal choice for industrial operators, municipal water authorities, and large commercial facility managers.
Engineered for high-volume water metering, our horizontal woltmann water meter delivers exceptional flow performance, with nominal flow rates ranging from 40 m³/h (DN80) up to 250 m³/h (DN200). This large flow capacity makes it perfectly suited for main water distribution lines and industrial facilities with high water consumption, ensuring accurate measurement even at peak flow rates.
The wet dial design with magnetic transmission eliminates mechanical wear between the measuring element and the counting mechanism, ensuring long-term measurement stability and accuracy. The sealed number roll system provides clear, direct readings, while the Class B accuracy rating complies with international metering standards, delivering consistent results for billing and operational monitoring.
Our flange connection bulk water meter features a removable measuring insert, allowing for on-site maintenance and calibration without removing the entire meter body from the pipeline, significantly reducing downtime and maintenance costs. Pre-equipped mounting points for pulse emitter devices enable easy upgrade to remote reading capabilities even after installation, eliminating the need for full pipeline retrofits.
Manufactured with first-class corrosion-resistant materials, these meters feature a robust metal body, brass sealing ring, and anti-corrosion coating, ensuring long service life even in harsh water quality and working environments. With a maximum working pressure of 1.6Mpa, they are built to withstand continuous operation in municipal and industrial water supply systems.

The overload flow rate ranges from 80 m³/h (DN80) up to 500 m³/h (DN200), with a nominal flow rate of 40 m³/h to 250 m³/h, designed to meet high-volume water metering demands.
Yes, the meter is pre-equipped with mounting points for impulse emitter devices, allowing for easy installation of pulse output modules even after the meter has been installed in the pipeline.
All models of this wet dial magnetic woltman water meter use standard flange connection, with full dimensional details provided to ensure compatibility with existing industrial pipeline systems.
Wet dial meters have the counting mechanism fully immersed in water, delivering enhanced stability in high-flow conditions, while dry dial meters isolate the counter from water. Wet dial designs are preferred for large-flow industrial and municipal applications where long-term measurement stability is critical.
