TOTAL- A
1.1
UNIT
This setting is used to select the engineering unit for the indication of the
(accumulated) totals, both for input A and B, and the pulse output.
When you change the engineering unit, you must recalculate and
reprogram the K-factor for the (accumulated) total. When you recalculate
and reprogram the K-Factor, the history for (accumulated) total is not
correct anymore, because the (accumulated) total is not recalculated. For
future reference, best practice is to make a note of the accumulated total
before you program the recalculated K-Factor.
1.2
DECIMALS
This setting is used to set the amount of digits behind the decimal point for
the (accumulated) totals indication, both for input A and B.
1.3
K-FACTOR
This setting is used to set the K-Factor for the total of input A. 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 engineering unit, for example m
3
. A more accurate K-Factor (more
decimals, as set in decimals K-Factor) allows for a more accurate
operation of the system.
Example 1: Calculating the K-Factor.
The flowmeter generates 2.4813 pulses per liter and the selected unit is
m
3
. A cubic meter consists of 1000 liter which gives 2.4813 pulses*1000
liter=2481.3 pulses per m
3
. So, the K-Factor is 2481.3. Enter for the
Flowmeter K-Factor: 24813 and for the flowmeter K-Factor decimals: 1.
Example 2: Calculating the K-Factor.
The flowmeter generates 6.5231 pulses per gallon and the selected
engineering unit is gallons. So, the K-Factor is 6.5231. Enter for the
Flowmeter K-Factor: 65231 and for the Flowmeter K-Factor decimals: 4.
When you recalculate and reprogram a new K-Factor, the history for
(accumulated) total is not correct anymore, because the (accumulated)
total is not recalculated. For future reference, best practice is to make a
note of the accumulated total before you program the recalculated K-
Factor.
1.4
DECIMALS K-
FACTOR
This setting is used to set the amount of digits behind the decimal point for
the K-Factor setting for input A.
3.3.3 MENU 2 - FLOW RATE - A
The settings for total and flow rate are entirely separate. In this way, different engineering units can
be used for each e.g. cubic meters for total and liters for flow rate.
2
FLOW RATE - A
2.1
UNIT
This setting is used to select the engineering unit for the indication of the
flow rates of input A and B.
Alteration of the engineering unit will have consequences for operator and
setup values, they will not be automatically recalculated to the value of the
new selected unit. The K-Factor has to be adapted as well; the calculation
is not done automatically.
2.2
TIME
This setting is used to set the time unit for the flow rate calculation of inputs
A and B. Note that the flow rate is given in engineering unit/time unit, e.g.
liters/minute (l/min).
When you change this setting, also recalculate and change the settings for
the analog rate-min and analog rate-max.
