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.
The calculator calculates the volume of water integrating the measured flow rate during the time and
indicates the data in display.
Water meter calculator provides all the 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 required for reporting annually and monthly date to be determined; set day parameter
values
- Archive data storage time 36 months, including the calculated volume and tariff register;
- Detection of errors;
- Displaying of values of parameters ( optional) and displaying of faults
- Verification and service functions.

5.3.2. Mounting of flow sensors
Sizes and mounting dimensions of flow sensors are provided in Annex B.
Requirements for flow sensor installation in pipeline:
- For water meters with flow sensors DN65…DN100 necessary straight pipelines lengths are:
upstream straight pipeline length must be not less 5DN and downstream straight pipeline length
must be not less 3DN ( flow profile sensitivity class U5 D3)
- For water meters of other sizes no requirements for straight pipeline length in upstream and
downstream directions ( flow profile sensitivity class U0 D0)
Avoid the flow sensor installation near after the pumps which can cause cavitations.
Flow sensor can be mounted both vertically and horizontally in pipelines or on an incline.
If flow direction in the pipeline is from top to down, the pipeline must be under pressure.
The direction of the sensor installation (is indicated with the arrow on flow sensor) must match
with the flow direction in pipeline.
The flange 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. Setting up the jumpers (J)
The connector J is on the calculator plate pulse input / output connection terminals (Figure A1).
Joining or leaving open the connector contacts, you can choose the normal or verification (test) mode,
activate the pulse inputs or outputs:
5.5. Verification of installation and set-up
After installing the water meter, let measured fluid flow through the flow sensor. Measured
parameter values should be indicated on the display, if the water meter (calculating unit, flow sensor is
installed correctly). If measured parameter values are not displayed correctly, it is necessary to verify the
installation.

Description
Status of calculator
0 - no error, normal operation
1 - warning –ending battery life
8- electronics failure
Status of temperature sensor
(if used )
0- no error, normal operation
4- short circuit
C- open circuit
Status of flow sensor
0- no error, normal operation
1- no signal, flow sensor is empty
2- flow flows in an reverse direction
4- flow rate greater than 1.2∙Q4 (are displayed q=1,2 Q4)
8- electronics failure

Active error codes are added and simultaneously displayed, if it is detected more than one error
3 - corresponds errors 2 + 1
5 - corresponds errors 4 + 1
7 - corresponds errors 4 + 2 + 1
9 - corresponds errors 8 + 1
A - corresponds errors 8 + 2
B - corresponds errors 8 + 2 + 1
C - corresponds errors 8 + 4
D - corresponds errors 8 + 4 + 1
E - corresponds errors 8 + 4 + 2
F - corresponds errors 8 + 4 + 2 +1
In a case when value at least one digit of error code is ≥ 8 - calculation of thermal energy and
summation of volume of water and operation time without errors are stoping
In the case of the flow sensor error "4" - duration of time, "when the flow rate q> 1.2 ∙ Q4" is
registered in addition.
6.4. Activating test mode
Destination of contacts of connector J
The 2-line,10-pole connector is on the calculator plate between temperature sensors and pulse input
/output terminals (see fig.A1, Annex A). Destination of contacts of connector J is presented in fig. 6.3.

Activation of test (verification) mode
In test mode it is possible to achieve precise results within short measuring time.
For activation of Verification (Test) mode you must opening device and set up jumper on the
connector (J) contacts as shown in Figure 6.4.
Fig. 6.4. Test mode activation
For working in this mode, the calculator can not be closed.
When the jumper “J” is set, the device enters test mode – label “TEST” appears on the LCD,
calculation process is stopped and all integral parameter values are saved in the memory. After return to
normal mode, the original values from before the test are displayed again.
The readings of meter in verification (test) mode are presented in p. 6.3.2
LCD resolution in verification mode „TEST“ is 00,000001 m3
Volume pulse values in verification mode „TEST“ are presented in Table 6.1

Ending of verification mode
Remove jumper J to leave test mode and return to normal mode. After leaving test mode,
previously recorded integral parameter values are displayed.
6.5. Remote data reading
6.5.1. For data transmission from meter it can be used optical interface (EN 62056-21). The
optical head is placed on the calculator and is connected to interface of reading device.
In addition for remote reading of data can be used two pulse outputs, or one of the following
communication modules:
M-Bus
CL (Current loop)
RF-module 868 MHz
LON
MODBUS RS485
MiniBus
The pulse outputs are active when the corresponding contacts of connector (J) are open (see Fig. 6.3)
All communication interfaces does not affect the measured parameters and their calculation, and
therefore can be replaced by another type without removing of verification seal.
Data collection from meters can be realized via PC, via telephone modem, via GSM modem, via
Internet, and so on.
7. VERIFICATION
Metrological control of water meter parameters is performed according to requirements defined in
EN 14154.
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 possibility to shift inside vehicle.
Meters should be protected against mechanical damage and shock.
Meters should be stored in dry, heated premises, where environment temperature is not lower
than +5 oC. No aggressive chemical substances should be stored together because of corrosion hazard.
