Precision Volumetric Water Measurement
Designed to meet stringent ISO 4064 standards, this DN20 volumetric water meter utilizes advanced piston displacement technology to deliver exceptional measurement accuracy. Unlike velocity-based meters, its volumetric measuring principle ensures that a precise volume of water is physically trapped and measured, significantly reducing non-revenue water loss. With a design optimized specifically for vertical installation, it provides utilities, sub-metering contractors, and property managers with a highly reliable solution for precise consumption monitoring and billing.
Engineered for Extreme Environments
Built to withstand challenging physical conditions, this water meter boasts a premium IP68 protection class, making it completely dust-tight and capable of continuous underwater operation. The core mechanism features a liquid-filled, hermetically sealed register that entirely prevents dial fogging and condensation, keeping the numbers crystal clear for the duration of its lifespan. Furthermore, the built-in anti-magnetic protection safeguards the device against external tampering, ensuring the absolute integrity of your measurement data under maximum working pressures up to MAP16.
Key Features & Advantages:
- High Accuracy Class R200: Delivers an exceptional measurement range with an ultra-sensitive starting flow of just 6.67 L/h, guaranteeing that even the smallest drips are recorded accurately up to a permanent flow rate of 4.0 mÂł/h (Q3).
- Liquid-Filled Register: The hermetically sealed IP68 design ensures the display remains permanently legible and unaffected by humidity, effortlessly handling water temperatures of T30/T50.
- Anti-Magnetic & Tamper-Proof: Integrated magnetic shielding secures the meter against fraudulent external interference, guaranteeing dependable and secure data for utility billing.
- Standardized DN20 Fit: Features industry-standard BSP G1B threading and a compact 154mm length, allowing for seamless and secure integration into existing threaded pipeline infrastructures.
