High-Capacity Accuracy for Demanding Water Systems
This DN40 volumetric water meter is designed for applications that require dependable measurement under higher flow conditions. Built on advanced piston displacement technology, it delivers stable and precise performance across a wide operating range, making it well suited for multi-unit residential buildings, commercial facilities, and centralized water distribution systems. With Class B (R250) accuracy, the meter ensures reliable consumption tracking while supporting more transparent billing and better resource management. Its Q3 flow rate of 16 mÂł/h makes it an efficient choice for installations where larger water demand must be measured without sacrificing consistency.
Sealed Construction for Long-Term Reliability
Engineered for harsh installation environments, this model features a dry dial and hermetically sealed register that protect the reading mechanism from condensation, moisture, and dirt. The robust IP68 protection class enhances durability in wet, dusty, or underground conditions, while anti-magnetic protection helps maintain data integrity and reduces tampering risks. Designed for horizontal installation with a threaded BSP G2B connection, it offers practical compatibility for larger pipeline systems. Compliance with ISO 4064 further confirms its suitability for professional metering projects that demand accuracy, durability, and trusted quality.
Key Features & Advantages:
- High-Flow Measurement Stability: Designed with a Q3 capacity of 16 mÂł/h, this meter performs reliably in systems with substantial daily water consumption while maintaining consistent volumetric accuracy.
- Durable Sealed Protection: The combination of IP68 housing and a hermetically sealed dry dial register ensures clear reading visibility and dependable operation in challenging environments.
- Smart Upgrade Potential: With AMR-ready capability, the meter can be integrated into remote reading systems, supporting smarter management and more efficient utility operations.
