13.4 Setting the parameters of the volume flow rate
13.4.1 Giving a user defined name to the measured volume flow rate
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.
By default, the name associated to the measured volume flow rate is Volume flow .
To add a user defined name to the default name, do the following:
→ Select the device in the navigation area.
→
SAW sensor
→ Parameter
→
Stand. meas. values
→ Volume flow
→
Value name
→ Enter the name. The name can have up to 19 characters.
→
Apply
The name is changed.
13.4.2 Activating the damping of the volume flow rate values and
selecting a predefined damping level
The damping makes it possible to damp the fluctuations of the measured values of the volume flow rate:
• on the totalizers,
•
on the outputs. The damping set for an analog output comes in addition to the damping of the volume
flow.*
)
• on the liquid velocity value. The damping of the volume flow comes in addition to the damping set for the
liquid velocity.
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 measured volume flow rate values are damped with the level Medium .
The low damping level or no damping at all ( None ) are suited for applications/processes that need fast
response times.
The medium damping level or the high damping level are suited if the flow rate values change slowly.
→
As an alternative to the 3 predefined damping levels Low , Medium or High , you can set your own
damping parameters. See chpt. 13.4.3.
*) Only variant with outputs.
