Explanations of the SETUP functions
6.4.1
TOTALIZER – 1
Measurement unit - 11:
SETUP - 11 determines the measurement unit for total and accumulated total. The following units can be selected:
L - m3 - kg - lb - GAL - USGAL - bbl - _ (no unit).
Alterations 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.
Number of decimals displayed - 12:
The decimal point determines for total and accumulated total the number of digits following the decimal point. The following
can be selected:
0000 - 111.1 - 22.22 - 3.333
K-Factor - 13:
With the K-factor, the flow meter pulse signals are converted to a quantity. The K-factor is determined on the basis of the
measurement unit and the number of pulses generated per unit by the flow meter. Enter the number of pulses generated by
the flow meter per selected measurement unit (per cubic meter e.g.). The more accurate the K-factor, the more accurate the
functioning of the system will be.
Number of decimals displayed for K-Factor - 14:
This function determines the number of decimals for the K-factor (see 13). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 – 6
Please note that this function influences the accuracy of the K-factor indirectly. This setting has NO influence on the displayed
number of digits for total (SETUP 12)!
Example 1:
Calculating the K-factor.
Let us assume that the flow meter generates 2.4813 pulses per litre and the selected unit is "cubic metres / m
3
". A cubic metre
consists of 1000 parts of one litre which implies 2,481.3 pulses per m
3
. So, the K-factor is 2,481.3. Enter for SETUP - 13:
"2481300" and for SETUP - 14 - decimals K-factor "3".
Example 2:
Calculating the K-factor.
Let us assume that the flow meter generates 6.5231 pulses per gallon and the selected measurement unit is gallons. So, the K-
Factor is 6.5231. Enter for SETUP - 13: "6523100" and for SETUP - 14 decimals K-factor "6".
