Aquadis Rotary Piston Volumetric Type Water Meter
Aquadis is an mid 2004/22/EC approved piston type water meter for residential and commercial and indusrial billing applications.
The Technology
Aquadish combines the advantages of piston type technology together with proven reliability of the extra dry register, no gear is in contact with water.
The high technology implemented to manufacture measuring chamber ensures stable and durable accuracy of aquadis meter.
Metrological Performances
– Very low starting flow allows leakage getection
– Large measuring range
Robustness :
- Robust hermetically sealed IP68 register TVM (Copper Can/Mineral Glass Enclosure) to face all field situations, DN 20/25/30 in option and DN 40/60/65 in standard
- Plastic register TSN equipped with wiper to ensure readabiy in tough humid condisions (standart for DN 20/25/30)
- Maximum admissible working pressure in 16 bar
Easy Reading - Rotations close to 360 degree on site
- Large numbered rollers with good contrast for excellent reding capability
Communication Device
Pre-equipment for fiture communication through cybe.
Working Principle
The aquadish has two main component : The hydraulics that allows measurement of the water and the register that displays the measured water volume.
Transmission interface between those component is achieved by a strong magnetic coupling :
- Aquadish is a piston type volumetric meter
- Each rotation of the measuring chamber presents a given volume of water pissing through, with extra dry-register
- Gear are protected by water and air proof enclosure
Communication :
The Aquadish Is Supplied Pre-Equipped With Cyble Target
Allows communication and remote reading through :
- Pulse Output (cyble sensor)
- M-Bus Protocol (Cybe M-Bus)
- Radio Frequensi Wireless Link (Cybe RF)
Key Advantages of Cybe Technology
- No Need for additional on the meter to implement remote reading
- Itron standardized meter interface, irrespective of meter technology and widely spread on itron water meters range
- Reabilility bhrought by electronic switch (no wear or bouncing)
- Reverse flow management
- Principle propen on the field with a 20 years exprerience
- Pre-equipped being immune to magnetic tampering
