Reliable Flow Measurement for Upgraded Capacity

Engineered for consistent and accurate utility monitoring, this Multi-Jet Dry Dial Water Meter delivers robust performance for residential and light commercial applications. Designed with a standard DN20 (20 mm) threaded connection (BSP G3/4B), it allows for straightforward horizontal installation in existing pipelines. Strictly compliant with ISO 4064 standards, this velocity-type meter guarantees dependable volumetric tracking with a highly stable Class B (R100) accuracy rating. It effectively manages a robust permanent flow rate of 4.0 m³/h and is sensitive enough to detect starting flows as low as 13.3 L/h, ensuring every drop is accounted for across a maximum reading capacity of 99,999 m³.

Rugged Anti-Tamper Design and Smart Integration

Constructed to withstand harsh utility environments, this meter boasts an IP68 protection class. Its hermetically sealed dry dial completely isolates the register from the water flow, strictly preventing condensation and guaranteeing crystal-clear readability over decades of use. To protect your revenue, the highly efficient magnetic drive transmission is fortified with built-in anti-magnetic protection, actively stopping external tampering and data manipulation. Furthermore, this meter is future-proofed for modern grids; its AMR Ready architecture allows for seamless integration into automated meter reading networks for efficient remote data collection.

Key Features & Advantages:

  • Exceptional Precision: Features an R100 turndown ratio, accurately capturing minimum flow rates down to 40 L/h for exact and reliable billing data.
  • Condensation-Free Display: The IP68 hermetically sealed dry dial ensures the register remains completely dry and legible, eliminating internal fogging even in damp or flooded pits.
  • Secure & Efficient Operations: Designed with active anti-magnetic protection to prevent utility theft, while maintaining an ultra-low pressure loss of ≤0.063 MPa under a working pressure of up to MAP16.
