EXPLANATION OF SETUP-FUNCTIONS
1 - PRESET
MEASUREMENT UNIT
11
SETUP
11 determines the measurement unit for preset, 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 preset, 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 represents 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 "2481300" for
SETUP
- 13: Next enter “3” for
SETUP
- 14.
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 "6523100"for
SETUP
- 13:
Next enter “6” for
SETUP
- 14.
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)!
BATCH MAXIMUM
15
This function limits the operator to enter a new preset-value which is more
as the entered batch maximum.
