Step by Step: Flow Calibration entering the G factor
Flow calibration is determined by the geometry of the specific VFC orifice. Each VFC orifice is
calibrated at the factory when it is manufactured. The calibration process determines a single value that
characterizes the flow properties of the orifice. This value is called the G Factor (the G factor is printed
on the serial number tag on the VFC device and is also printed on the VFC device look up table). The
VFC+ requires this G Factor in order to calculate the flow rate. This value is entered using the
following procedure:
1. Press the ‘F3’ to enter the SETUP menu.
2. Press the ‘ENT’ key to acknowledge the warning message concerning SETUP.
3. Select the CALIBRATE menu item and press ‘ENT’.
