What follows applies to both operating modes of the flowmeter.

9.1 Calibration

Rate reading may not be correct due to different system configurations (tubes,
valve, etc.). Therefore, we recommend to make a spray test; in case the measured
value is different from the real one, perform an automatic calibration procedure or
manually calculate flowrate constant.

9.1.1

Automatic calibration

Make a quantity of liquid previously measured or that can be measured with another system
go through the flowmeter

. The greater the amount of liquid used to perform the calibration

procedure, the more accurate the calibration.

End reading

0.0 l/min

1) Access Automatic calibration menu (Setup menu > Calibration >
Auto calibration).

Once inside the menu, the device is ready to

start measuring without any further controls.

2) Make the liquid go through the system. The display will start to
show the increasing value of the measured quantity of liquid. Once
liquid passage has finished, the value on the display will not change
any more.
At this point, press OK. In the lower part of the display, the mes-
sage Stabilization will come up and the device will show
the screen on the side.

Display of liquid amount read by the flowmeter during calibration procedure.

3) Using the keys, enter the values of the liquid quantity previously measured:

A)

Press to toggle from one digit to another

B)

Press in succession to modify the value of the digit highlighted by the cursor

C)

Press to complete calibration procedure, or

D)

Press for 1 sec. to cancel calibration procedure.

If, after starting calibration, the device does not sense any flow passage (and the display
remains in 0), press

OK

to exit the calibration procedure without saving.

If the device continues to sense the liquid flow after pressing

OK

, after a few seconds

the error message Stop flow!will be displayed.
Once the flow has been interrupted, the reading will stabilize as by standard procedure.
