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 and leakage detection;
- Displaying of values of parameters ( optional) and displaying of faults
- Verification and service functions.

6.3.3. Error codes
Error code may consist from up to 4 symbols.
Code
Description
1st digit
0- no error, normal operation
1- air in the measuring section
2- flow flows in an reverse direction
4- flow rate greater than 1.2∙Q4(are displayed q=1,2 Q4)
2nd digit
0- no error, normal operation
4- short circuit
C- open circuit
3rd digit
0 - normal operation
1 –leakage (q > 0 more then 24 h)
2 -burst (q > 0,2*Q3more then > 0,5 h)
4- the battery was disconnected
4th digit
0 - no error, normal operation
1 - warning –ending battery life (less than 6 months left)
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. Activation of test (verification) 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.

Fig. 6.3. Destination of contacts of connector J
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

PEF1IP68V04 2017 11 20
19
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 meter parameters is performed according to requirements defined in EN 4064.
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.
No aggressive chemical substances should be stored together because of corrosion hazard.
9. WARRANTY
