Details of Setup Functions
1 – TOTAL
MEASUREMENT UNIT
11
SETUP 11 determines the measurement unit for total, accumulated total and pulse output The options are: L,
m 3 , 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 the number of digits following the decimal point for total, accumulated total and
pulse output
The options are: 0000000, 111111 1, 22222 22, 3333 333
OTEE: N Setup 15 offers a multiplication factor If the volume measured is very high it is advised to use the
multiplication factor and to select 0000000 decimals for SETUP 12
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 / m 3 "
A cubic meter consists of 1000 parts of one liter which implies 2481 3 pulses per m 3 So, the K-factor is 2481 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 US gallon and the selected measurement unit is
US 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) You can select from 0 to
6 decimals:
This setting indirectly influences the accuracy of the K-factor (that is, 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)!
MULTIPLICATION
FACTOR
15
In applications where very large volumes are measured, it is desired to use a multiplication factor for the
displayed totalizers This to avoid a fast “turning to zero” The ER-420 will divide the real totalized volume with
this factor and display the result Following multiple factors can be selected and will be displayed for the
Operator
The options are: x1, x10, x100, x1000, x10000
For the Operator, the valid factor is displayed after pressing SELECT twice This factor does not influence the
flow rate
THIS MULTIPLICATION FACTOR APPLIES ALSO ON PULSE AND OUTPUT (SETUP 72).
