Totalizer Exponent
TOTL E — Flow Totalizer Exponent Value (Choice)
E(–1)…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 × 10
n
multiplier, where “n” can be from –1 (× 0.1)…6 (× 1000,000).
Table 8 should be referenced for valid entries and their influence on the display.
Selection of E-1 and E0 adjusts the decimal point on the display. Selection of E1, E2
and E3 causes an icon of × 10, × 100 or × 1000 respectively to appear to the right of
the total flow display value.
Table 8: Exponent values
Minimum Flow Rate
MIN RATE — Minimum Flow Rate Settings (Value)
A minimum rate setting is entered to establish filter software settings and the lowest rate value that will be displayed.
Volumetric entries will be in the rate units and interval selected previousley. 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.
OTE:N The flow meter will not display a flow rate at flows less than the MIN RATE value. As a result, if the MIN RATE is set to a
value greater than zero, the flow meter will display the MIN RATE value, even if the actual flow/energy rate is less than
the MIN RATE.
For example, if the MIN RATE is set to 25 and actual rate is 0, the meter display will indicate 25. Another example, if the
MIN RATE is set to -100 and the actual flow is -200, the meter will indicate -100. This can be a problem if the meter
MIN RATE is set to a value greater than zero because at flows below the MIN RATE the rate display will show zero flow,
but the totalizer which is not affected by the MIN RATE setting will keep totalizing.
Maximum Flow Rate
MAX RATE — Maximum Flow Rate Settings (Value)
A maximum volumetric flow rate setting is entered to establish filter software settings. Volumetric entries will be in the rate
units and Interval selected previousley. 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.
