Description
SCALE F
Scale factor value (Enter a numeric value)
The SCALE F function applies a correction factor/multiplier to the readings and outputs so
the DFX system can agree with a different or reference flow meter, or to compensate for an
installation where there is inadequate straight pipe to obtain a laminar flow profile A factory
calibrated system should be set to 1 000 The range of settings for this entry is 0 5000…5 000 The
following example describes using the SCALE F entry
The DFX meter is indicating a flow rate that is 4% higher than another flow meter located in the
same pipe line To have the meter indicate the same flow rate as the other meter, enter a SCALE F
of 0 960, to lower the readings by 4%
DAMPING
System damping
percentage
(Enter a numeric value
0…99%)
Flow Filter Damping establishes a maximum adaptive filter value Under stable flow conditions
(flow varies less than 10% of reading), this adaptive filter increases the number of successive flow
readings that are averaged together up to this maximum value If flow changes outside of the
10% window, the Flow Filter adapts by decreasing and allows the meter to react faster Increasing
this value tends to provide smoother steady-state flow readings and outputs
CFG MOD1
Configure I/O
Module
YES or NO
This prompt lets you access the setup parameters associated with installation of the optional
ISO-MOD interface modules If NO is selected, the unit skips ahead to CFG MOD2 If YES is
selected, configuration and calibration of the module installed in the first position is accessible
CFG MOD2
Configure I/O
Module
YES or NO
If NO was selected at CFG MOD1, CFG MOD2 becomes active This prompt lets you access the
setup parameters associated with installation of the optional ISO-MOD interface modules If NO
is selected, the unit skips ahead to PASSWORD If YES is selected, configuration and calibration of
the module installed in the second position is accessible
