Reliable High-Flow Measurement for Residential and Light Commercial Use

This DN20 volumetric water meter is designed for applications that require precise measurement, stable operation, and dependable long-term performance. Using advanced piston displacement technology, it delivers highly accurate registration across both low and normal flow conditions, making it ideal for residential buildings, apartment systems, and light commercial water distribution. With Class B (R400) accuracy and a low starting flow of 3.33 L/h, the meter helps capture small consumption volumes more effectively, supporting fair billing and better water usage control. Its Q3 flow rate of 4.0 mÂł/h also makes it well suited to installations that demand consistent performance under higher daily consumption.

Sealed Construction for Harsh Installation Conditions

Built for durability, this model features a dry dial with a hermetically sealed register, protecting the reading mechanism from moisture, condensation, and dirt. The IP68 protection class ensures reliable operation in wet, dusty, or underground environments where ordinary meters may struggle. For added security, the meter includes anti-magnetic protection, helping preserve measurement integrity and reduce tampering risks. Compliant with ISO 4064, and equipped with a threaded BSP G1B connection, it offers a practical combination of installation convenience, measurement stability, and trusted product quality.

Key Features & Advantages:

  • High-Accuracy Performance: The R400 volumetric metering system ensures precise reading of both low and regular water flow, improving billing accuracy and water management efficiency.
  • Rugged Sealed Design: A hermetically sealed dry dial and IP68 body provide dependable protection in challenging installation environments.
  • Smart Upgrade Ready: The AMR-ready design allows easy integration with remote reading systems, making it a future-oriented choice for modern utility projects.
