16.7 Profile correction
The following settings can be made for the calculation of the fluid mechanics calibration
factor k
Re
:
• off : profile correction 1.0
• on : profile correction 2.0 at ideal inflow conditions (default)
• With disturbance : profile correction 2.0 at non ideal inflow conditions
The following steps are necessary to set the profile correction:
• Selection of the profile correction setting for all measuring channels in the program
branch Special Funct.
• Input of the disturbance distance in the program branch Parameter if
With disturbance has been selected
If
With disturbance
has been selected, the transducers have to be mounted in
reflection arrangement, X arrangement or displaced X arrangement to compensate
transverse flow effects. When mounting in X arrangement, it is essential to set the same
parameters for both measuring channels and to activate for them a calculation channel
with average generation.
Selection of the setting
• Select the menu item Special Funct. in the program branch Measuring .
• Press ENTER until the menu item ProfileCorr 2.0 is displayed.
• Select a list item (default:
on
).
• Press ENTER.
