2.4 EXTERNAL COMMUNICATION MODULES AND INTERFACES
Optical interface is integrated in Qalcosonic
W1 meter by default. It is intended for data
reading, changing parameters of meter and for
outputting optical pulses
in the test (verification) mode. It is activated by
sending 1 second pulse sequence (5 minutes
after the end of communication is
automatically deactivated).
There is also NFC (Near Field Communi cation)
interface integrated by default. It is intended
for data reading only.

5INSTALATTION
5.1 GENERAL REQUIREMENTS
PRIOR TO INSTALLING THE METER, IT IS NECESSARY:
• to check the complete set of the meter with that specified in the technical documentation.
• to check for any visible mechanical defects.
• to check the configuration of the meter and to change it if necessary.
T he meters may only be installed by qualified specialists in accordance with the requirements of this document and the meter installation
design.
5.2 CHECKING CONFIGURATION OF THE METER
Prior to installing the meter, it must be verified whether its configuration complies with the requirements for the specific facility and it must be
changed if necessary.
THE FOLLOWING PARAMETERS ARE VERIFIED (THE FACTORY SETTINGS FOR THE METER ARE THEIR STANDARD ONES):
• volume measurement units
• displayed volume resolution (point position)
• additional customer serial number (if applied)
• internal clock time (with optical head and special tools)
NOTE. The transportation mode will turn off and radio will be activated automatically when the meter starts operation and the volume totalizer
has accumulated more than 10 liters.
5.3 CHECKING OF INSTALLATION AND PARAMETER SETTING
If meter is installed correctly, when there is water flow, the display of the meter should display flow readings.
It is necessary to check whether the meter is installed in the correct direction, also - whether there is no air in the system .

axiomametering.com

5.4 MOUNTING
Temperature of the working environment
should not be higher than 70°C.
No special requirements are established for
the free space around the meter. It is
important that nearby installations or
structures do not rest against the housing of
the meter and do not interfere with reading
the data from the display. The meter should
be installed at a safe distance from other
devices emitting heat or strong
electromagnetic field (to prevent disturbance
of its working environment conditions).
Sizes and mounting dimensions of meter are
provided in Annex A and B.
Straight pipelines in upstream and
downstream from the meter are not required
(flow profile sensitivity class is U0 D0).
Water meters may be installed in all position
(either horizontally, vertically or inclined).
Mandatory condition: pipe must be
pressurized to not less than 30 kPa. For
proper preparation the pipe must be filled
with water.
Direction of the arrow on the meter must
match flow direction in pipeline. Lateral
tension force should be avoided, pipe ends
must be aligned together.
To avoid stresses in the pipelines, the
distance between the meter connection
points in the meter installation place shall
correspond to the total length of meter with
regard to the thickness of gaskets.
It is recommended to select meter
installation place as far as possible from
potential sources of vibration (for example,
pumps).
The gaskets must match with the pipe
diameter. During the installation, gasket must
be exactly centered with the center of the
pipe cross-section to avoid sticking out
gaskets inside the pipe.
Tightening toque should not excide the value below:
