The settings for total and flowrate are entirely separate. In this way, different units of measurement
can be used for each e.g. cubic meters for total and liters for flowrate.
The display update time for flowrate is one second or more.
Note: these settings also influence the analog output.

1 - TOTAL

SETUP 11 determines the measurement unit for total, accumulated total
and pulse output.
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 K-factor has to be adapted
as well; the calculation is not done automatically.
The decimal point determines for total, accumulated total and pulse output
the number of digits following the decimal point.
The following can be selected: 0000000; 111111.1; 22222.22; 3333.333
With the span, the flowmeter signal is converted to a quantity.
The span for Total is determined on the basis of the measurement unit
(setting 11) and the flowrate per second at 20mA.
Enter the span in whole numbers (decimals are set with SETUP 14).
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 - 13: "004314" and for SETUP - 14 "6".
Example 2 Calculating the Span.
Let us assume that the flowmeter generates 20mA at a
flowrate of 2,481.3 Liters/minute and the selected unit is "cubic
meters / 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 - 13: "041355" and for SETUP - 14 - decimals
span "6".
This setting determines the number of decimals for the Span
(SETUP 13). 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 12)!

2 - FLOWRATE

SETUP 21 determines the measurement unit for flowrate.
The following units can be selected:
L; m3; mg; g; kg; ton; GAL; bbl; lb; cf; rev; - - - - (no unit); scf; Nm3; Nl; P; mL
Alteration of the measurement unit will have consequences for operator
and SETUP-level values. Please note that the K-factor has to be adapted
as well; the calculation is not done automatically.
The flowrate can be calculated per second (SEC), minute (MIN), hour
(HR) or day (DAY).
This setting determines for flowrate the number of digits following the
decimal point. The following can be selected:
0000000; 111111.1; 22222.22; 3333.333
