adjustment Designed with 4 sections of correction, divided into four flow
points and four correction coefficients.
The corresponding velocity of correction point must meet
:
Correction point 1 ≥ Correction point 2 ≥ Correction point 3 ≥ Correction
point 4 ≥ 0
Correction calculation is conducted on the original sensor flow
coefficient curve correction, therefore, the nonlinear correction function
shall be disabled and sensor coefficient shall be marked. Then enable
the nonlinear correction function according to the nonlinear of sensor
and set correction coefficient for sectionized correction. If the coefficient
is set right, there is no need for calibration. The original velocity stands
for the actual flow velocity, and the revised flow velocity is called
modified velocity, the modified computation formula is as follows:
At the interval of the modified point 1
＞
The original flow velocity
≥ The modified point 2
The modified flow velocity = Correction factor 1 × The original
flow velocity
At the interval of the modified point 2
＞
The original flow velocity
≥The modified point 3
The modified flow velocity = Correction factor 2 × The original
flow velocity
At the interval of the modified point 3
＞
The original flow
velocity ≥ The modified point 4
The modified flow velocity = Correction factor 3× The original flow
velocity
At the interval of the modified point 4
＞
The original flow velocity ≥
0
The modified flow velocity = Correction factor 4× The original flow
velocity
Note: when set the modified point, shall keep the following relationship
Modified point 1

Modified point 2

point 4

The intermediate value of correction coefficient is 1.0000, if the
