process. When the static fluid is more than 20 seconds, the left side of the window will
display “1”; Then open the valve, “P” will be flashing, means during the calibration process,
calibration accumulator to Zero and begin to count immediately. When meet the
requirement of accumulative flow value, close the valve, flow will be reduced gradually until
the “P” without flashing, it will display “1” when the fluid in stationary states. Finish the
above process, you can read out the calibrate value from the accumulator, divide water
volume of the standard container, that is the relative error. For the start-stop method, the
start duration should be more than 60 seconds each time. The shorter duration, the more
relative error caused.
3.2 Constant-Current Method
Constant-current method be defined at the set of flow point, make the calibration
device(standard water meter) and tested water meter into stable flow state, is a calibration
method by the measured accumulative flow at the same time.

window display capital letter “C”. Constant-current method is no need the static flow. When
flow stable, press ““, calibration accumulator begin to count, lowercase letter “c” will be
flashing, when require to stop, press ““ again.
In the calibration window, second line on the display is average instantaneous flow
rate of the calibration period time, rather than the instantaneous flow rate instantly. Its
formula is : average instantaneous flow rate= accumulative flow rate of calibration period
time ÷ calibration period time.In the constant-current window, press “ “, means exiting
and entering into start-stop method window
According to the simulate keypad operation, also can achieve the constant-current
method calibration by RS485 or infrared interface. Calibrate accumulator valve and
calibrate accumulator operation time can be read out by computer and calculate the
relative error automatically, there is the correction factor, which will download to the water
meter automatically to realize calibration process automation.

value is effective only when pipe with full liquid and water meter powered on after 1~ 2
minutes.
For the dual channel, it will display two channel signal strength alternative.
In general, it means no error if the last eight digits is “0”; it need to “decode” according
to the above table to check the fault if the last eight numbers appears none “ 0”
For example, “400000100” means fault in channel 1, “400000200” means fault in
channel 2, “000000304” means fault in both channel
For example, “40000A006” means open circuit for both temperature transducer, the
similar false default will appear when treat the flow meter as heat meter without the
temperature transducer.
If you are familiar with the Hexadecimal encoding，It’s easy to find out the fault. Also
you can download the software “V49_ERRCODE.EXE” to get the meaning of the error from

Note 1： （1）For all cumulants, a long integer represents the integer part and a real number represent the
decimal part. In most applications, users just need to read the long integer part, do not have to read the
decimal part.
If N means the long integer value(for example the positive accumulated flow, the bit value of 32 in REG
0009,0010 is a long integer)
Nf means the decimal part(for example the positive accumulated flow, 32 bit floating point number in REG
0011, 0012)
n means the decimal point position (for example the accumulated flow, REG 147).
Then,
The final total accumulated flow = (N+Nf ) ×10-n
REG 148 value range from 0~3, determines the unit of accumulated flow.
0 cubic meter (m3)
1 liter (L)
2 American gallon (GAL)
3 Cubic feet (CF)
For example, if REG0009=123456789, REG0010=0.123, and REG147=3, REG148=0
Then the total flow = 123456.789123 m3
For heat accumulator：
The energy flow rate =(N+Nf )×10n-4
n is determined by REG01440.
Unit of accumulated heat is determined by REG 1441.
Note 2： REG361 is specially designed for communication test. If the number you read in REG361 is
not 361.0, but ‘0’ or ‘250.264’, which means your read address is wrong. Please consult relevant
MODBUS protocol standard. More details could be found on Internet.
Note 3： The register of software version and manufacturer is used to identify the register table.
