The desired flow characteristics may be changed using this function. E.g. If a valve with linear
inherent flow characteristic is used and equal percentage applied flow characteristic is selected, the
valve will be act as an equal percentage valve.
The adjacent number is the rangeability of the valve. The rangeability of the valve may be found in
the manufacturer's documentation. The options for applied flow characterization are:
LINEAR,
TABLE, EP25, EP33, EP50, QO25, QO33, and QO50
The equation resulting from its curve is:
Y (%) = (X/ (((X (%). /100)*(1-L)) +L)),
Where:
Y [%] = Value after the flow characterization curve calculation and X [%] = Position value before
entering in the curve calculation.
L = Characterization Factor
Enter the input and
output values.
Allows the reading of
configurable table.
After configuring the points, this key
must be pressed to verify if the table
is monotonous increasing.
