15.9.3 Activating a user-defined damping of the liquid density values
The damping makes it possible to damp the fluctuations of the measured values of the liquid density:
• on the display,
• on the outputs. The damping of the liquid density comes in addition to the damping set for each analog
output (see chapter 18.3.2 ).
• The damping of the liquid density comes in addition to the damping set for the mass flow rate.
To damp the fluctuations of the measured values, you can:
→
either choose 1 of the 3 predefined damping levels:
Low
,
Medium
or
High
. See chapter 15.9.2 .
By default, the measured liquid density values are damped with the level
Medium
.
→
Or you can set your own damping parameters with the Special damping.
With the Special damping, you can set 2 parameters:
• a user-defined Response time in seconds,
• the Jump threshold , i.e. a user-defined percentage. If 2 consecutive measured values vary for ± the per -
centage, no damping is applied to the second measured value.
To set your own damping parameters of the measured liquid density values, do the following:
→
Go to the CONFIGURATION view.
