– TOTAL
Total and flowrate are configured independently.
Both have their own K-factor and measurement unit.
Example: Calculating the K-factor.
To manually calculate the K-factor to enter for total or flowrate, follow this example:
Assume that the flowmeter generates 65.231 pulses per US gallon and the required measurement
unit is cubic foot / ft
3
. A cubic foot consists of 7.48052 gallon which implies 487.9618 pulses per
cubic feet. So, the K-Factor to enter is 487.9618.
1 TOTAL
1.1 UNIT
This setting determines the measurement unit for (Accumulated) Total
and the scaled pulse output.
The following can be selected:
L
– m3 – kg – LB – GAL – USGAL – bbl – (no unit).
1.2 DECIMALS
The decimal point determines for Total and Accumulated Total the
number of digits following the decimal point.
The following can be selected:
0
– 0.1 – 0.02 – 0.003
1.3 K-FACTOR
With the Total K-Factor, the flowmeter pulse signals are converted to
a total unit. The Total K-Factor is based on the number of pulses
generated by the flowmeter per selected measurement unit
(SETUP 1.1). Use SETUP 1.4 to set the decimal point.
The more accurate the Total K-Factor, the more accurate the
functioning of the system will be.
1.4 K-FACTOR DECIMALS
This decimal point determines for K-Factor (SETUP 1.3) the number
of digits following the decimal point.
The following can be selected:
0
– 0.1 – 0.02 – 0.003 – 0.003 – 0.0004 – 0.00005 – 0.000006
3.3.3 MENU 2
– FLOWRATE
Changes to SETUP 2.1 Unit, SETUP 2.2 Time unit and SETUP 2.3 Decimals have an effect
on the analog output settings of SETUP 4.2 Rate Min and SETUP 4.3 Rate Max.
Therefore it is best practice to first determine the required settings for the flowrate!
2 FLOWRATE
2.1 UNIT
This setting determines the measurement unit for flowrate.
The following can be selected:
mL
– L – m3 – g – kg – ton – GAL – bbl – lb – cf – none
2.2 TIME
The flowrate can be calculated per /sec - /min - /hour - /day.
2.3 DECIMALS
This setting determines for flowrate the number of decimals.
The following can be selected:
0
– 0.1 – 0.02 – 0.003
2.4 K-FACTOR
With the Flowrate K-factor, the flowmeter pulse signals are converted
to a flowrate unit. The Flowrate K-factor is based on the number of
pulses generated by the flowmeter per selected measurement unit
(SETUP 2.1).
The more accurate the K-factor, the more accurate the functioning of
the system will be. Use SETUP 2.5 to set the decimal point.
The more accurate the Total K-Factor, the more accurate the
functioning of the system will be.
