High-Precision Single Jet Measurement

This DN25 Single Jet Dry Type water meter is engineered for optimal accuracy and reliability in residential and commercial applications. Operating on a precise velocity-type measuring principle, it ensures consistent flow monitoring with a high Class B (R100) accuracy rating. Fully compliant with ISO 4064 standards, this device features a horizontal installation design that makes it an industry-standard choice for accurate water management. It comfortably handles a permanent flow rate (Q3) of 6.3 mÂł/h while maintaining an incredibly low starting flow of just 13.13 L/h, seamlessly capturing even the smallest water usage to prevent revenue loss.

Built for Extreme Durability and Smart Integration

Designed to withstand harsh operational environments, this meter boasts an IP68 protection class, ensuring long-term performance and reliability even in fully submerged conditions. It is fortified with robust anti-magnetic protection, preventing external tampering and ensuring complete billing integrity. Built for the future of utility networks, this device comes AMR ready with optional pulse output, allowing for effortless integration into modern smart meter reading systems and remote data monitoring setups.

Key Features & Advantages:

  • Hermetically Sealed Register: The dry dial utilizes a vacuum-sealed register, keeping the display completely free from frost or condensation to ensure absolute reading clarity over its entire lifespan.
  • Optimized Flow Dynamics: Achieves a broad measuring range with an R100 ratio and effortlessly manages an overload flow rate (Q4) of 7.875 mÂł/h, all while minimizing pressure loss to ≤0.063 MPa.
  • Versatile Compatibility: Features standardized G1 1/4B BSP threaded connections and operates safely within MAP16 pressure and T30/T50 temperature classes, making plug-and-play installation straightforward across various municipal piping networks.
