Dwyer GFT2 - Manual (Page 13)

An optional cables kit assembly is available for order:
c) Input/Output Jumper Configuration
NOTE: The GFT2 device input/output jumpers were configured at the factory
according to the order. There is no need to change input/output jumpers
configuration unless a different input is being used. Before applying power and
process signals, make sure the input/output jumpers are installed in the correct
positions. See Table 6.
d) Parameters Configuration
The following parameters must be configured:
• Device Function (see Submenu “Device Function”). “Meter function has to be
selected.
• Full-Scale Range (see Submenu “Device Calibration”). Full-Scale Range
parameter has to be set equal to the GFM full-scale flow rate in L/min.
• Fluid Std. Density (see Submenu “Device Calibration”). This parameter is required
only when mass-based engineering units are selected.
NOTE: If “Full-Scale Range”, “Device Function”, and “Fluid Std. Density”
parameters are not set properly, the device may have erroneous readings and
unpredictable behavior.
User may configure other parameters according to individual preferences and
application requirements.
