8.Installation
8.1. Hazard warnings
The meter must be installed without mechanical stress in the pipe. A mechanically stressed installation may lead to the destruction of the meter
housing. This would cause water to escape.
The pipe pressure must not be higher than the pressure specified on the rating plate. Excessive pressure can lead to leakages or destruction of
the meter housing. This would cause water to escape.
8.2. General information
The Cordonel meter may only be installed by a qualified and instructed specialist. The generally accepted rules of technology and the applicable
safety regulations must be observed at all times (in particular, the notes contained in standard ISO 4064-5:2014).
The meters are disinfected after the production process. Handling during installation must be carried out in accordance with applicable hygiene
rules. We refer in particular to VDI/DVGW Guideline 6023 Section 6.7 and 6.8 and DVGW Worksheet W557 Section 5. Before installing the me-
ter, it must be disinfected again. We recommend removing the meter from the transport packaging at the actual measuring point shortly before
installation.
Install the meter in such a way that no forces greater than 100 kg can act on any of the plastic parts.
8.3. Required tools
Two wrenches or hexagon socket wrenches, both corresponding to the nominal size of the bolts used. In some cases, suitable lifting gear.
The variable parameters are programmed by radio using the Sensus SIRT radio interface and the Diavaso config app from Sensus.
8.4. Installation positions
The meter can be installed in horizontal and vertical pipes. It should be installed in such a way that the LCD is easy to read.
Do not install the meter with the display facing downwards or with the display upside down.
