DATA IN QALCOSONIC W1 METER CAN BE TRANSMITTED USING THE FOLLOWING PROTOCOLS:
•wMBus T1
•wMBus S1
•wMBus C1
•SIGFOX
•LORA WAN
•CoAP
All communication interfaces are intend-
ed for data reading and meter parametri-
sation. The meter is produced for being
powered only from the internal battery. In
order to save the battery, communication
credit system is implemented into the
meter. Time of communication through
additional interfaces is automatically lim-
ited to save the battery (up to 20 minutes
per month). Unused communication limit
is summed up. If the limit is expired, the
interface is blocked and the new time
limit of communications will start only af-
ter the change of the hour (16 seconds for
each next hour).
Optical interface is integrated in Qal-
cosonic W1 meter by default. It is intend-
ed for data reading, changing parameters
of meter and for outputting optical pulses
in the test (verification) mode. It is activat-
ed 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.

3 OPERATING PRINCIPLE
WATER METER PERFORMS ALL NECESSARY MEASUREMENT AND DATA STORAGE FUNCTIONS.
BELOW ARE THE MOST IMPORTANT:
•High stability in measuring water volume and detection characteristics of overload
•Calculation of the maximum values and their storage in archive
•Storage of necessary data for reports on set day yearly and monthly
•Archive data storage time 36 months
•Detection of faults
•Displaying values of parameters (optional) and displaying info codes
•Verification and service functions
Flow measuring principle is based on
ultrasonic measurement method. Ultra-
sonic signal moves along the measuring
section many times and the flow down-
stream between the ultrasonic sensors
have to perform transmitter and receiver
functions. From the results of time dier-
ence the flow rate is calculated and indi-
cated in display.

It is recommended to select meter instal-
lation place as far as possible from po-
tential 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.
5.4 CHECKING OF INSTALLATION AND PARAMETER SETTING
If meter is installed correctly, the display of the meter should display flow readings (when there is flow).
It is necessary to check whether the meter is installed in the correct direction or there is no air in the system.
6 OPERATION
WATER METER IS EQUIPPED WITH 2LINE LCD LIQUID CRYSTAL DISPLAY:
Upper line with 9-digits for displaying measured volume of water.
Lower line with 5-digits for displaying current flow rate and special symbols for displaying operation modes.
6.1 DISPLAY FUNCTIONS
FLOW ARROW MEANINGS:
flow is flowing forward
flow is flowing
backwards*
arrow is not displayed flow does not flow
SPECIAL SYMBOLS ON LCD:

and an error code is also sent, due to backflow.
The direct water volume summation record remains
unchanged (unless chosen dierently).
Error symbol is shown when there is a significant meter operation error. For the info code, see the LCD menu item 1.7 in
paragraph 6.2.

The indication of irrelevant parameters can be turned o. Also, parameters that are not relevant to the set meter configuration will not
be indicated.
The indication of parameters can be turned on or o by means of the configuration software „W1 TOOL“ through the optical interface
when installing the meter (if the meter is in the transportation mode).

In verification (test) mode it is possible to achieve precise results within short measuring time.
In the test mode, the meter:
• indicates the increased resolution of flow values.
• forms volume pulses through the optical interface.
Volume pulse values (via optical interface) in verification mode „TEST“ are presented in the table below.
PERMANENT FLOW RATE Q3, M3/H VOLUME
PULSE VALUE, L/IMP
1,6 0,3
2,5 0,3
40,3
Using an optical head and PC with W1
TOOL software the meter verification
mode (TEST) can be activated.
Optical head should be connected to
the computer USB interface. After plac-
ing optical head on the meter with the
special holder and opening the program
start up window, PC port number (to
wich optical head is connected) is en-
tered in the field „Com Port“. Click „Wake
up meter“ button, then click the „Enter
test mode“ button. When the meter TEST
mode is activated, meter readings are
displayed with resolution of 1 ml. Optical
pulse output of meter might be used or
volume indications could be read direct-
ly from LCD.
6.8 ENDING OF VERIFICATION MODE
Using an optical head and PC with W1 TOOL software the meter verification mode (TEST) is returned to the operating mode. After
opening the program startup window, click „Wake up meter“, then click „Enter user mode“. The meter returns to the normal mode.
Also, meter returns to its normal mode automatically in 24 hours after activation of TEST mode.
7 VERIFICATION
Metrological control of meter parameters is performed according to requirements defined in EN ISO 4064-1.
8 TRANSPORTATION AND STORAGE REQUIREMENTS
Packed meters may be transported in any type of covered vehicle. Equipment should be anchored reliably to avoid shock and possi-
bility to shift inside vehicle. Meters should be protected against mechanical damage and shock. No aggressive chemical substances
should be stored together because of corrosion hazard.
• Storage and transportation temperature: from -25°C to 70°C (drained flow part)
• Humidity: not more than 93%
