EXPLANATION OF SETUP-FUNCTIONS
1 - TOTAL
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).
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.
DECIMALS
12
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
K-FACTOR
13
With the K-factor, the flowmeter pulse signals are converted to a quantity.
The K-factor is based on the number of pulses generated by the
flowmeter per selected measurement unit (SETUP 11), for example per
cubic meter. The more accurate the K-factor, the more accurate the
functioning of the system will be.
Example 1:
Calculating the K-factor.
Let us assume that the flowmeter generates 2.4813 pulses per
liter and the selected unit is "cubic meters / m3". A cubic meter
consists of 1000 parts of one liter which implies 2,481.3 pulses
per m3. 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 flowmeter 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".
DECIMALS K-FACTOR
14
This setting determines the number of decimals for the K-factor entered.
(SETUP 13). The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this setting influences the accuracy of the K-factor
indirectly. (i.e. the position of the decimal point and thus the value given)
This setting has NO influence on the displayed number of digits for total
(SETUP 12)!
