2. Installation Instruction
2.1 Choose the installation point
Straight pipe installation requirement(D is pipe diameter), upstream ≥3D, downstream 0D,
make sure the pipe full of liquid completely.
Correct installation point Wrong installation point
At the lowest point in the pipe system;
Vertical upward or slanted upward pipe;
Upstream straight pipe≥3D
At the highest point in the pipe system;
Vertical downward or slanted downward
pipe; Upstream straight pipe＜3D
ps：Arrow direction is fluid flow direction.
2.2 Installation Method
1.Confirm installation dimension
2.Cup off
Water meter length L+2pcs sealing gasket thickness+10mm
3.Install matching flanges
4.Flanges position
5.Flanges welding
6.After cooling, install with sealing gasket,
fasten screws
Three screws on an average positioning flanges,
spot-welding fixing
Take off the water meter,
finish full welding of the flange

3. Calibration Method
There are two kinds of calibration method of T3 water meter, including the start-stop method and constant-current method
3.1 Start-Stop Method
Start-stop method be defined in the stationary states, start and stop the calibration device(standard water meter) and tested
water meter simultaneously, is a calibration method by the measured accumulative flow
Please go to Menu 05, you are no need to operate the keypad during the calibration 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.
Please go to Menu 05, press “
 
“ into constant-current window. the lest side of the 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 formular 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.
