EXPLANATION OF SETUP-MENU 1 - TOTAL
SETUP
FUNCTIONS
AND
VARIABLES
1
TOTAL
1.1
UNIT
Determines the measurement unit for total and accumulated total. The
following units can be selected:
L - m3 - kg - lb. - GAL - USGAL - bbl - _ (no unit).
Alteration of the measurement unit will have consequences for
operator and SETUP-level values.
Please note that the Span has to be adapted as well; the calculation
is not done automatically.
1.2
DECIMALS
The decimal point determines for total and accumulated total the
number of digits following the decimal point.
The following can be selected:
0000000 - 111111.1 - 22222.22 - 3333.333
1.3
SPAN
With the span, the flowmeter signal is converted to a quantity. The
span for Total is determined on the basis of the selected
measurement unit (SETUP 1.1), and
the flow rate per second at
20mA
. Enter the span in whole numbers; decimals are set with
SETUP 1.4. The more accurate the span, the more accurate the
functioning of the system will be.
Example 1
Calculating the span
Let us assume that the flowmeter generates 20mA at a rate of 652.31
USGAL per hour, the selected unit is barrels. There are 42 gallons in
one barrel; so the rate is 652.31/42 is 15.53119 barrels/hour.
This is 0.0043142 barrels/second, which is the span.
Enter for SETUP 1.3: "004314" and for SETUP 1.4: "6".
Example 2
Calculating the span
Let us assume that the flowmeter generates 20mA at a flow rate of
2,481.3 Liters/minute and the selected unit is
“m3".
The rate per second is 2,481.3/60 is 41.355 L/sec. This is 0.041355
m3/sec., which is the span.
Enter for SETUP 1.3: "041355" and for SETUP 1.4: "6".
1.4
DECIMALS SPAN
This setting determines the number of decimals for the Span
(SETUP 1.3). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this function influences the accuracy of the Span
indirectly. This setting has NO influence on the displayed number of
digits for total (SETUP 1.2)!
3.3.3
EXPLANATION OF SETUP-MENU 2 - FLOW RATE
The settings for total and flow rate are entirely separate. In this way, different units of measurement
can be used for each e.g. cubic meters for total and liters for flow rate.
The display update time for flow rate is one second or more.

FLOW RATE
2.1
UNIT
SETUP 2.1 determines the measurement unit for flow rate.
The following units can be selected:
mL - L - m3 - mg - g - kg - ton - GAL - bbl - lb - cf - REV - ---- (no unit)
- scf - Nm3 - NL - P.
Alteration of the measurement unit will have consequences for
operator and SETUP-level values.
Please note that the span has to be adapted as well; the calculation is
not done automatically.
2.2
TIME UNIT
The flow rate can be calculated per second (SEC), minute (MIN), hour
(HR) or day (DAY).
2.3
DECIMALS
This setting determines for displayed flow rate and span the number
of digits following the decimal point.
The following can be selected:
00000 - 1111.1 - 222.22 - 33.333
