Select a desired engineering unit for flow accumulator (totalizer) measurements.
24. Totalizer Exponent
TOTL E -- Flow Totalizer Exponent Value (Choice): E(-1) to E6
Utilized for setting the flow totalizer exponent. This feature is useful for
accommodating a very large accumulated flow or to increase totalizer resolution
when flows are small (displaying fractions of whole barrels, gallons, etc.) The
exponent is a × 10n multiplier, where “n” can be from –1 (× 0.1) to +6 (×
1,000,000). Reference table 4.4 for valid entries and their influence on the display.
Selection of E-1 and E0 adjust the decimal point on the display. Selection of E1, E2 and
E3 cause an icon of Ч 10, Ч 100 or × 1000 respectively to appear to the right of the
total flow display value.

25. Minimum Flow Rate
MIN RATE -- Minimum Flow Rate Settings (Value)
Enter a minimum rate setting to establish filter software settings and the lowest
rate value that will be displayed. Volumetric entries are in the Rate Units and Interval
selected previously in this section. For unidirectional measurements, set MIN RATE to
zero. For bidirectional measurements, set MIN RATE to the highest negative (reverse)
flow rate expected in the piping system.
Note: The flow meter does not display a flow rate at flows less than the MIN RATE value.
For flow rates less than the MIN RATE, the flow meter displays the MIN RATE value
continuously.
26. Maximum Flow Rate
MAX RATE -- Maximum Flow Rate Settings (Value)
Enter a maximum volumetric flow rate setting to establish filter software settings.
Volumetric entries are in the Rate Units and Interval selected previously in this
section. For unidirectional measurements, set MAX RATE to the highest (positive)
flow rate expected in the piping system. For bidirectional measurements, set MAX
RATE to the highest (positive) flow rate expected in the piping system.
27. Low Flow Cut-off
FL C-OFF -- Low Flow Cut-off (Value): 0-100%
A low flow cut-off entry is provided to allow very low flow rates (that can be present
when pumps are off and valves are closed) to be displayed as zero flow. Typical values
that should be entered are between 1.0% and 5.0% of the flow range between MIN
RATE and MAX RATE.
28. Damping Percentage
DAMP PER -- System Damping (Value): 0-100%
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 the number of averaged readings, allowing the meter to react
faster. Increasing this value tends to provide smoother steady-state flow readings
and outputs. If very erratic flow conditions are present or expected, other filters
are available for use in the software utility. See Part 5 of this manual for further
information.
CH1 Menu -- Channel 1 Menu
1. CH1 MENU -- 4-20 mA Output Menu
4-20 MA -- 4-20 mA Setup Options (Values): FL 4MA (Flow at 4 mA), FL 20MA (Flow
at 20 mA), CAL 4MA (4 mA Calibration), CAL 20MA (20 mA Calibration), 4-20 TST (4-20
mA Test)
The CH1 menu controls how the 4-20 mA output is spanned for all models and how
the frequency output is spanned for the non-BTU flow model.
The FL 4MA and FL 20MA settings are used to set the span for both the 4-20 mA
output and the 0-1000 Hz frequency output on the non-BTU meter versions.
The 4-20 mA output is internally powered (current sourcing) and can span negative
to positive flow/energy rates. This output interfaces with virtually all recording and
logging systems by transmitting an analog current proportional to the system flow
rate. Independent 4 mA and 20 mA span settings are established in firmware using
the flow measuring range entries. These entries can be set anywhere in the -40 to
+40 FPS (-12 to +12 MPS) range of the instrument. Resolution of the output is 12-bits
(4096 discrete points) and they can drive up to a 400 Ω load when the meter is AC
powered. When powered by a DC supply, the load is limited by the input voltage
supplied to the instrument. See Figure 3.1 for allowable loop loads.
