ITRON Aquadis+ DN20 Water Meter – Volumetric Piston Meter (Brass, 190 mm, G 1")
Looking for a water meter with uncompromising precision and an exceptionally long service life? The Itron Aquadis+ is a high-quality volumetric piston water meter designed to maximize water volume measurement over time. Thanks to its advanced piston principle, it registers even the smallest water flows that traditional meters miss, making it the ideal choice for billing and leak detection in residential and commercial properties.
Why Choose a Piston Meter Over a Standard Meter?
Unlike traditional Woltman or multi-jet meters (velocity meters) that require water to reach a certain speed to start turning a wheel, the Aquadis+ operates on a volumetric piston principle. This means physical measuring chambers are mechanically filled and emptied.
- Registers Flows Close to Zero: The meter features an extremely low starting flow rate of just 2 liters per hour. It begins tracking and registering volume at the first sign of a dripping faucet or a leaking toilet.
- High Precision in Any Position: This model is approved for R150, guaranteeing full metrological precision (with an error margin within +/-2%) down to 16.6 liters per hour. Because it is a volumetric meter, it maintains this high accuracy whether installed horizontally, vertically, or inclined.
Smart Metering Ready – Built for the Future
The Aquadis+ comes equipped with Itron’s proven Cyble target. This means that at any point—either upon delivery or as a future retrofit—you can simply clip on a communicating Cyble module for remote AMR/AMI reading.
- Compatible with modern data collection systems such as LoRaWAN, Sigfox (Cyble4ioT), wireless M-Bus (OMS), and pulse outputs.
- The electronic detection principle does not wear out, eliminates pulse bounces, and is completely insensitive to external magnetic fields, preventing any risk of tampering or fraud.
Robust and Maintenance-Free Construction
- Hermetically Sealed Register (IP68): The counter is encased in a copper can and equipped with a heavy-duty mineral glass lens. It is entirely condensation- and waterproof, ensuring perfect readability throughout the meter's entire lifespan. No parts of the register ever come into contact with the water flow.
- Brass Body: A heavy and robust metal casing providing exceptional resistance to pressure shocks.
- Built-in Filter: The meter features an integrated, easy-to-clean filter designed to capture major particles in the water supply and protect the internal measuring mechanism.
- Non-Return Valve Compatible: The meter body is fully compatible with an optional spring-loaded non-return valve installed at the outlet (EN 13959).
