4.2 Installing the G-Flow display
4.3 Installing the G-Flow pulse outlet
The G-FLOW meter with display is delivered pre-calibrated by the manufacturer and ready for
installation.
The G-FLOW PULSE Outlet version has a calibrated pulse outlet; the meter must be connected with the 3
cables, as shown in the diagram, and the electrical specifications must be respected.

4.4 Installing the G-Flow reed outlet
The G-FLOW REED Outlet version has a non-calibrated pulse outlet; the meter must therefore be
connected with the 2 cables, as shown in the diagram, and the electrical specifications must be respected.
Electrical specifications:
Max voltage
: 200 VDC - 140 VAC
Max current
: 0.5 ADC – 0.35 ADC

5 - INTENDED USE
5.1 Main screens
The device automatically switches on when dispensing starts or when either the Reset key (R) or the Total
key (T) is pressed once. The display automatically switches off if no operation is performed or if no signal
is detected for 120 consecutive seconds. Each time the meter is switched off the “Partial” screen is reset,
therefore it does not need resetting at the first refuelling after switch-off. When the flow meter is switched
on it displays the “Partial” screen, which is the screen it automatically returns to if no key is pressed for 10
seconds. There are five main screens you can navigate through simply by pressing
, plus the log of the
last five refuelling operations carried out, which you can navigate through simply by pressing
.
Starting on the “Partial” screen, press
to navigate through the last five refuelling operations carried
out. To go back to the home screen wait for 10 seconds without pressing any key.

Important:Do not use conical connections that can damage the body of the meter or the
connection flange. When installing position the suction filter.
Important: Due to the different operating conditions, pre-calibration may be different
than the one required; it is therefore recommended to calibrate the meter with each
installation (see CHAP. 6).
