15.8 Setting the parameters of the liquid velocity
15.8.1 Giving a user defined name to the measured liquid velocity
The name is used to identify the process value in the user defined views and in all the menus where the
process value is displayed (for example in the Outputs menu).
By default, the name associated to the measured liquid velocity is
Liquid velocity
.
To add a user defined name to the default name, do the following:
→
Go to the
CONFIGURATION
view.
→
SAW sensor
→
Confirm to access the Parameter view.
→
Stand. meas. values
→
Liquid velocity
→
Value name .
→
Enter the name by selecting and confirming each character. The name can have up to 19
characters.
→
OK
→
Save the name.
The name is changed.
15.8.2 Activating the damping of the liquid velocity values and
choosing a predefined damping level
The damping of the liquid velocity comes in addition to the damping set for the volume flow. The damping
makes it possible to damp the fluctuations of the measured values of the liquid velocity:
• on the display,
• on the outputs. The damping of the liquid velocity comes in addition to the damping set for each analog
output (see chapter 18.3.2 ).
The damping is not applied to the new measured value, if the 2 following conditions are met:
• a
Low , Medium or High damping level is active,
• and the variation between 2 values that are measured one after the other is higher than 30 % (for example
when charging the pipe or stopping the flow).
By default, the liquid velocity values are not damped.
→
As an alternative to the 3 predefined damping levels Low , Medium or High , you can set your own
damping parameters. See 15.8.3 .
