Our intelligent bulk water meter (Model: LXLN-50-300) is a high-performance flow measurement solution engineered for commercial, industrial, and large-scale irrigation applications. Designed and manufactured by a leading Chinese high-tech enterprise with over 1.5 million annual meter production capacity, this DN50-DN300 industrial water meter delivers reliable, high-accuracy water consumption monitoring for high-flow scenarios. Featuring a dry dial magnetic transmission structure, this meter complies with both DIN and ANSI international standards, making it a versatile choice for business clients across Europe, Africa, the Middle East, and Southeast Asia. With a diameter range from Ø50mm to Ø300mm (2” – 12”), our bulk water meter is optimized for minimal pressure loss, ensuring stable operation even in continuous high-flow water supply systems. Pre-equipped with an impulse emitter interface, it seamlessly integrates with smart water management systems, supporting digital monitoring for facility operators and water supply project contractors.
This dry dial magnetic transmission water meter delivers industry-leading measurement precision, with an error margin of ±5% in the low flow zone (from minimum flow rate qmin to transitional flow rate qt, exclusive boundary) and ±2% in the high flow zone (from qt to overload flow rate qs). The hermetically sealed dry dial design prevents fogging and wear, ensuring long-term clear reading and stable performance even in humid industrial environments. The magnetic transmission structure eliminates mechanical contact between the measuring element and the register, reducing friction and extending the meter’s service life.
Engineered with a tangential measuring structure, our irrigation water meter is specially optimized for agricultural and landscape irrigation systems, with minimal pressure loss to reduce energy consumption for water supply pumps. The meter supports cold water measurement up to 50°C, with a maximum working pressure of 1.6Mpa, adapting to most municipal and industrial water supply network requirements. The wide diameter range covers almost all high-flow commercial and industrial scenarios, with customizable options available for specialized project needs.
To meet the demands of modern smart water management, this intelligent industrial water meter comes pre-equipped with an impulse emitter device interface, enabling seamless connection to remote monitoring and data acquisition systems. This feature allows business clients to achieve real-time water consumption tracking, leak detection, and billing management, reducing operational costs and improving water use efficiency. We also offer full customization services, including OEM and ODM solutions, to match specific project requirements.
