While filling out the table, write in the column T [C°] the temperature shown on the screen,
measured by the Coriolis flow meters.
While spraying at different temperatures, the calculated values of the output are corrected adding
a ∆ term obtained multip
lying the difference in temperature between the value in the table and the
actual temperature for the coefficient K. ∆ = (Ttable
–Tactual)*K
In the table above for instance, in the recipe 1, with a requested set point of 170 ml/min interpolating
the data the calculated output to the regulator is 31.8% at 20.5 °C.
Spraying at 25°C ∆ = ( 20.5
-25 )*0.8 = - 3.6 and the corrected output 31.8 - 3.6 = 28.2 [%].
The value of K, has to be determined experimentally; generally the values of K are positive: at a
defined flow setup the greater is the temperature, the lower is the output regulator value needed.
Start with a zero value of K and rise it gradually to compensate the temperature effect on the values
previously saved in the table.
Write zero in the temperature T and K columns if the temperature compensation is not needed.
If the system is equipped with an EcoCleaner M the table can be filled with an automatic quick
procedure.
Place the gun already loaded in the EcoCleaner M, login with user level two or higher.
