7. Set the parameter Viscosity compensation for the liquid:
• If the liquid is water, then make sure that the parameter Viscosity compensation is set to water . Refer to
chapter 15.15 .
• If the liquid has a kinematic viscosity that is between 0.5 and 2 mm
2
/s, then you can keep the parameter
Viscosity compensation to water . Refer to chapter 15.15 .
• If the liquid is not water or if the liquid kinematic viscosity is lower than 0.5 or higher than 2 mm
2
/s, then
set the parameter
Viscosity compensation
to a value that is adapted to the liquid properties and to the
process conditions. Refer to chapter 15.15 .
8. Set the parameter Refresh time to Short . Refer to chapter 15.16 .
9. To monitor the volume flow rate, set the parameter Damping of the volume flow rate:
• To measure a stable volume flow rate or to conduct a teach-in procedure depending on the volume flow
rate Teach-in by volume flow , set the parameter Damping of the volume flow rate to Medium . Refer to
chapter 15.4.2 or 15.4.3 .
• To fill containers on a time scale typically ≥ 30 s, set an appropriate damping of the volume flow rate.
Refer to chapter 15.4.2 , 15.4.3 or 15.4.4 .
• To fill containers on a time scale typically < 30 s or to conduct a Teach-in by volume , set the parameter
Damping of volume flow rate to None . Refer to chapter 15.4.4 .
10. To monitor the mass flow rate, set the parameter Damping of the mass flow rate:
• To measure a stable mass flow rate or to conduct a teach-in procedure depending on the mass flow
rate Teach-in by mass flow rate , set the parameter Damping of the mass flow rate to Medium . Refer to
chapter 15.5.2 or 15.5.3 . Set the parameter Damping of the density to Medium . Refer to chapter 15.9.4 .
• To fill containers on a time scale typically ≥ 30 s, set an appropriate damping of the mass flow rate.
Refer to chapter 15.5.2 , 15.5.3 or 15.5.4 . Set the parameter
Damping
of the density to
None
. Refer to
chapter 15.9.4 .
• To fill containers on a time scale typically < 30 s or to conduct a Teach-in by mass , set the parameter
Damping of mass flow rate to None . Refer to chapter 15.5.4 . Set the parameter Damping of the density
to None . Refer to chapter 15.9.4 .
11. To monitor the volume flow rate, make sure that the volume flow Cut-off function is active and set the
Cut-off value. Refer to chapter 15.4.9 or 15.4.10 .
12. To monitor the mass flow rate, make sure that the mass flow Cut-off function is active and set the
Cut-off value. Refer to chapter 15.5.9 or 15.5.10 .
13. To monitor the mass flow rate, calibrate
Density
by either using a teach-in procedure, either setting
offset and slope value of density. Refer to chapter 17.19 .
14. Set the parameter K factor . Refer to chapter 17.7 . The K factor applies to both process values volume
flow rate and mass flow rate.
15. There can be negative flows at the start or end of a batching step. By default, the counting directions
of the volume totalizers and mass totalizers and of the pulse outputs are set to Positive only and will
not take backwards flows into account. If necessary, depending on the rest of the batching system,
set the counting directions to Both directions . Refer to chapter 15.8.2 for volume totalizer, refer to
chapter 18.5.4 for pulse output, refer to chapter 15.11.2 for mass totalizer.
16. Check the correct behaviour of the device by using the menu Simulation . Refer to chapter 17.27 .
