TOTAL
1.1
UNIT
SETUP 1.1 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.
1.2
DECIMALS
This setting determines for total and accumulated total the number of
digits following the decimal point. The following can be selected:
00000 - 1111.1 - 2222.22 - 3333.333
1.3
K-FACTOR
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 1.1), for example
per liter. 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".
1.4
DECIMALS K-FACTOR
This setting determines the number of decimals for the K-factor
(SETUP 1.3). 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. This setting has NO influence on the displayed number of
digits for
“flow rate” (SETUP 1.2)!
