3.2.3. EXPLANATION OF SETUP-FUNCTIONS
1 - TOTAL
MEASUREMENT UNIT
11
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.
DECIMALS
12
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
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)!
