The water meter is a single-jet, dry dial water meter. The vane wheel is the only moving part in the water, and downshift occurs completely torrentially with magnetic coupling.
Scroll figures with 5 integers and 3 decimal places. The digit pulleys with decimals are red and with a minimum reading in liters.
The counter can rotate 355° to obtain a comfortable reading of the meter's roller digit. The meter's display board is protected against external magnetic impact according to EN 14154, throughout the measurement range.
The meter is prepared for connection of the remote reading module as shown below:
The composite meter, AT 7085, is, for example, used for "aggressive" water. Composite completely complies with the drinking water rules. The material results in lower energy consumption in manufacturing and gives 40% lower weight than the corresponding metal gauge.

The meter can be mounted both horizontally and vertically or with the numercial table facing the side. During a vertical mounting or mounting with the numercial table facing the side, a lower R-value (R40) and a higher Q2-value are obtained.
To ensure long-term operating of the water meter, always install a meter console (seeAccessories and options).
Shut-off valves should always be mounted to the console's inlets and outlets. The backflow protection after the water meter, should be a protection module type EA (controllable check valve) AT 1159 with a shut-off valve mounted on the inlet side. Before installing the water meter, it is important to clean the pipeline. Mount the meter with its flow arrows in the correct flow direction.
For installation of remote reading module, see product sheet 7275RES.
When installing remote reading modules, the sealed cover is removed and replaced with a remote reading module. Protective film on the module must be removed before the assembly. The supplied sealing tape is attached over the joint between the meter housing and the remote reading module to detect engagement or manipulation.
Remote reading modules: see seperate product sheet AT 7275RES
Spare parts to the meter are not provided, however remote reading modules are replaceable after the battery has run out.
The meters are marked with SENSUS Residia, manufacturing number with an EAN-code, size Q3, as well as a max. temperature of 30ºC resp. 90ºC.
The colour of the indicate-riser, indicates the temperature; Blue = Cold and Red = Hot.
