5 - LINEARIZE
The linearization function is available to approach the real flow curve better as with the general
K-factor (KF0) entered with setup 1.4 and 2.4. This to obtain a more accurate flowrate, total and
accumulated total as well as the analog and pulse output at any flowmeter frequency.
A maximum of 15 linearization-positions can be entered while the interpolation will calculate any
other position in-between.
For each linearization position, the frequency and a Meter Factor (MF) must be entered.
The Meter Factor for each frequency is calculated with following formula:
Meter-Factor =
K-Factor at flowrate X
KF0
The lowest frequency and MF you enter will be valid from 0Hz. The highest frequency and MF will
be valid till 10KHz. It is advised to enter the frequencies in increasing order, however it is not
necessary. Please have a look at following example to understand the method of linearization:
FREQUENCY /
M-FACTOR
5.1 TO 5.F
The frequency is displayed at the bottom line of the display.
The maximum frequency is 9,999.9 Hz. With value 0.0Hz, the M-Factor is
disabled. (Please read Setup function 5.H - decimals frequency)
The M-Factor is displayed at the top-line of the display. The minimum
value to be entered is 0.000001 and the maximum value is 9.999999.
Please note that this value has always six decimals while the "dot" is not
displayed.
Most M-factors will be around 1.000000 like 0.945354 or 1.132573.
DISABLE / ENABLE
5.G
With this setup function, you can easily enable / disable the linearization
function.
