High-Flow Woltman Metering for Bulk Water
Built for stable, high-volume measurement, this DN50 Woltman water meter is ideal for bulk supply lines in commercial buildings, industrial facilities, and municipal distribution. With R250 accuracy (ISO 4064), it delivers consistent, trustworthy readings across a wide operating range, helping utilities and contractors reduce disputes and improve billing confidence. The meter is designed to perform reliably at sustained high flow, while still capturing low-consumption periods with a precise minimum reading of 0.5L.
Dry Dial Clarity & Rugged Field Reliability
A sealed dry-type dial keeps the register isolated from the measured water, improving readability and supporting long-term stability in challenging conditions. The housing is engineered for harsh environments with IP68 protection, making it suitable for wet chambers and installations where immersion resistance matters. Its flange connection provides secure pipeline integration, and the specified installation orientation U10/D5 supports dependable performance when installed according to standard piping practices.
Key Features & Advantages:
- Bulk Flow Performance: Optimized for mainline measurement with strong continuous flow capability and smooth operation during demand peaks, while maintaining low hydraulic impact with pressure loss ≤0.063 MPa.
- Long-Life, Easy Reading: The protected dry register supports clear, reliable on-site reading and stable counting over time, with a large totalizer capacity of 999 999.999 mÂł.
- AMR Ready Upgrade Path: Optional AMR Ready output simplifies future smart metering integration for remote reading, data logging, and efficient network management without changing the meter body.
