The maximum permissible error (MPE), on volumes delivered at flow rate between the transitional flow rate Q2
(included) and the overload flow rate Q4(included) is:
- When water temperature ≤ +30 ºC 2 %
- When water temperature > +30 ºC 3 %
The maximum permissible error (MPE), on volumes delivered at flow rate between the minimum flow rate Q1
(included) and the transitional flow rate Q2(excluded) for water having any temperature is: 5%
If the flow-rate exceeds the maximum value Q4:
–when the flow-rate Q ≤ 1,2Q4, the flow-rate measurement and calculations are continued;
–when the flow-rate Q > 1,2Q4, calculations are performed using flow-rate value 1.2∙ Q4, the
info code “ Maximum allowable value of flow rate is exceeded ” is recorded and the duration of that status is
calculated.
Display (LCD)
The device is equipped with 2- lines LCD (Liquid Crystal Display):
Upper line - 9-digits for displaying measured volume of water:
Readings in normal mode: m3( three digits after decimal point).
Readings in verification (TEST) mode: m3( six digits after decimal point).
Lower line - 5-digits for displaying current flow rate, m3/h, and special symbols for displaying
operation modes
In the case of battery discharge, all integral readings and archive data shall be saved for at least 16
years and can be accessed by connecting a power battery in the operating condition.
Data recording and storage
In its memory, the meter accumulates an archive of hourly, daily, and monthly-measured parameters.
Archive data can be read only by remote data reading means (see Paragraph 6.5). The monthly data archive
parameters which are also additionally showed on the display are specified in Paragraph 6.3.1.
The following parameters of each hour, day, and month are accumulated in the memory of the meter:
1
Integral volume of water

Storage time of measured integrated parameters even if device is disconnected from power supply
not less than 16 years.
External communication modules and interfaces
Integrated in meter:
Optical interface
It is intended for data reading via Mbus protocol, parameterizing of meter, and for outputting optical
pulses in the test (verification) mode. It is activated by sending 1 s. pulse sequence (5 minutes after the end of
communication is automatically deactivated).
NFC (Near-field communication interface)
It is intended for data reading.
Ordered interface (to be specified when ordering the meter; one options can be selected only):
- RF 868 MHz

PL WQ1_180829
8
- RF 433 MHz
- RF 915 MHz
The data can be transmitted using the following protocols:
-W-M-Bus T1;
-W-M-Bus S1;
-W-M-Bus-C1;
-SIGFOX;
-LORA WAN;
Additional interface:
M-Bus interface (galvanically isolated, communication time is limited *)
Wired pulse output (galvanically isolated, pulse duration is limited)
The interfaces are intended for data reading and meter parametrisation. The meter is configured for being
powered only from the internal battery, and the time of communication through the additional interfaces is
automatically limited 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 after
the change of the hour (16 seconds for each next hour).
Pulse outputs

3 OPERATING PRINCIPLE
The flow measuring principle is based on ultrasonic measurement method. The ultrasonic signal along the
measuring section moves many times before, and the flow downstream between the ultrasonic sensors have to
perform transmitter and receiver functions. From the resulting time difference the flow rate is calculated and
indicated in display
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 data necessary for reports on set day yearly and monthly;
- Archive data storage time 36 months
- Detection of fault
- Displaying of values of parameters ( optional) and displaying of info codes
- Verification and service functions.
4 MARKING AND SEALING
Marking
There are following information on the front panel of the calculator of the meter - EC-type examination
certificate number, manufacturer’s trade mark , type of meter, year of manufacture and serial number,
permanent flow rate Q3and ratio R(Q3/Q1), temperature class, where is differs from T30, maximum admissible
working pressure (MAP), pressure loss class; installation sensitivity class of the meter, latest date by wich the
meter shall be replaced, software version number, IP code.
The following is indicated on the housing of meter:
–the type of connection (thread or relative diameter);
–the flow direction.
Sealing
The meter casing is imperceptibly closed. Any unautorized opening of the housing is impossible without
damaging. Additional manufacturer protection is not applied. The manufacturer's warranty does not apply if the
upper cover is opened or connection between upper cover and the housing is damaged.
When the upper sealed cover is opened, the safety button that installed in the meter body is activated
and error code appears on the meter display.
For sealing of meter after installation, there are provided holes in the meter body (See Annex B)
5 INSTALATTION
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.
The meters may only be installed by qualified specialists in accordance with the requirements of this
document and the meter installation design.
Check 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);
- set day of year and month;
- customer number
- internal clock time
- Mbus interface addresses and communication speed.
Note. The transport mode will turn off automatically (the possibility to change configuration parameters will be
turned off) when the meter starts operation and the volume integrator has accumulated more than 1 litre.

PL WQ1_180829

Mounting
The temperature of the working environment should not be higher than 70 oC.
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 (in order to prevent disturbance of its working environment conditions).
Sizes and mounting dimensions of meter are provided in Annex A.
The straight pipelines in upstream and downstream the mete ris not necessary (flow profile sensitivity class U0
D0).
It is recommended to install meters in pipelines as far as possible from pumps, partitions, and elbows.
Water meters may be in all position ( either horizontally, vertically or inclined).Mandatory condition: in the
operating mode, the pipe must have a pressure of not less than 30 kPa and the pipe must be fully filled with
water.
Direction of the arrow on the meter must match with the flow direction in pipeline.
In order 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.
Checking of installation and parameter setting
If the meter is installed correctly, when there is flow, the display of the meter should display flow readings.
It is necessary to check whether the meter is installed in the correct direction, whether there is no air in the
system.
