Bulk Water Measurement You Can Trust
Designed for stable performance in distribution mains and high-demand facilities, this DN50 Woltman water meter delivers dependable bulk metering with R250 accuracy and full ISO 4064 compliance. Its metering design supports consistent readings across changing demand patterns, making it a strong choice for utility billing, sub-metering, and industrial water management. For high-volume lines, it maintains measurement confidence while keeping system operation smooth and predictable.
Dry Dial Protection for Harsh Sites
The dry-type dial isolates the register from the measured water, helping protect readability and long-term counting stability in challenging environments. Built for field reliability, the housing features IP68 protection for wet chambers and installations where water exposure is unavoidable. A secure flange connection simplifies integration into standard pipelines, while the specified installation orientation U10/D5 supports accurate operation when installed to recommended upstream/downstream conditions. The meter also supports an optional AMR Ready output, enabling a practical upgrade path toward remote data collection without replacing the core meter.
