Compact Accuracy for Apartment & Residential Use

This volumetric water meter is engineered for precise consumption monitoring in apartment buildings, residential units, and other compact installation environments. Using advanced piston displacement technology, it delivers highly stable measurement performance even at very low flow rates. With an impressive R400 accuracy class and a starting flow of only 2.08 L/h, it can capture minor water usage more effectively, helping improve billing fairness and reduce unnoticed losses. Its DN15 size and short 80 mm body make it especially suitable for projects where space-saving installation is essential.

Built for Harsh Conditions and Long-Term Reliability

Designed for dependable operation, this meter features a dry dial with a hermetically sealed register, ensuring clear reading visibility while protecting the internal mechanism from moisture and contamination. The IP68 protection rating makes it ideal for demanding environments where water exposure, dust, or underground installation may be concerns. In addition, the built-in anti-magnetic protection enhances data security and reduces the risk of tampering. Compliant with ISO 4064, this model offers reliable performance, strong durability, and confidence for utilities, property managers, and system integrators.

Key Features & Advantages:

  • High-Precision Metering: The R400 performance level ensures accurate registration across low and normal flow conditions, making it ideal for precise residential billing.
  • Compact Installation Design: With a short 80 mm length, DN15 size, and threaded BSP G3/4B connection, it fits easily into tight meter boxes and apartment pipe systems.
  • Smart System Ready: The AMR-ready design supports future remote reading upgrades, helping users move toward more efficient and modern water management.
