The LXLC-50-200 Dry-dial Magnetic-drive Woltman Water Meter is a professional-grade industrial water meter engineered for high-volume water flow measurement in demanding commercial and industrial environments. Designed to comply with ISO 4064 Class B standards, this horizontal Woltman meter delivers reliable, long-term performance for total cold and hot water consumption monitoring, with a size range covering DN50 to DN200 (2” – 8”) to fit diverse pipeline requirements. Built with a robust iron cover and fully sealed mechanism, this bulk water meter is optimized for continuous operation in industrial and mining enterprises, ensuring accurate billing and water resource management for business clients.
This flange water meter adheres strictly to ISO 4064 Class B accuracy requirements, with a ±2% error margin in the high flow zone and ±5% in the low flow zone, delivering consistent readings for precise cost allocation and compliance monitoring for industrial operators.
The vacuum-sealed dry-dial register eliminates moisture intrusion and fogging, ensuring the numbered roll direct reading system remains clear and legible over decades of service, eliminating the need for frequent dial cleaning or replacement for enterprise customers.
With an optimized flow channel design, this industrial water flow meter features ultra-low head loss, reducing pumping energy consumption and operational costs for high-volume water distribution systems, a critical benefit for large-scale industrial facilities.
