AT 7420B is a water meter with a rotary piston measuring chamber design for cold water with an accuracy of R160. This means that the meter measures extremely thoroughly even at low flows. The design of the rotary piston meter allows mounting of the meter in any position with the exception of the meter body facing downwards. Piston meter AT 7420B doesn't have any after rotation. The meter has a self cleaning function and never goes against plus during its expiration time.
Piston meter AT 7420B is provided with indication display for connection of remote reading modules type Cyble, with M-Bus, wM-Bus and pulse. See separate product sheet AT 7275CY.
Cyble is an inductive AMR-system (Automatic Reading System) for remote reading and transfer of readings from the water meter to the measurement collection system. TheCyble-sensor's rotational frequency is read inductively through a metal fitted dial indicator.
Cyble-sensor can be mounted directly or at a later point, the meter's glass is prepared with attachment points with the help of the accompanying screws.
AT 7430B is made in composite. This means that the meter's manufacturing process is environmentally friendly through, among other things, less energy consumption and lack of heavy metalls like lead, zinc and copper. The material in the meter is 100% recyclable and has a high resistance against chlorine and other substances that can be found in drinking water. Composite has the same strength as brass but with a significantly higher elasticity, which make meter bodies in composite absorbing pressure stroke better without taking damage. The material's low weight also makes it easier to store, handle and transport.

Remote reading module type Cyble
The meter is provided with an indicator that registers meter readings, flow direction in a remote reading module type Cyble, that can be mounted on the meter glass. The Cyble-module can be ordered with pulse 1/10/100 liter per pulse, wM-Bus or M-Bus.
For more technical information see more in separate product sheet AT 7275CY.
