You don't get a lot of response to your question since it isn't clear what you want to know.
In the Ultimaker printers you don't have to calibrate the filament flow since the variation between printers is very small. Perhaps you think there is a problem with the filament flow and you are asking for a way to verify this?
If yes, then I don't know 'the best way', but there are a few maintenance tasks you can do:
If all this didn't help, then on the UM2(+) you might have a problem with the hotend insulator being degraded, this happens sooner when you print at temperatures > 250C. These hot end isolator couplers are sold all over the internet

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

If yes, then I don't know 'the best way', but there are a few maintenance tasks you can do:
- Clean the nozzle: https://ultimaker.com/en/resources/19510-how-to-apply-atomic-method
- Verify the feeder tension is set to the middle of the allowed range (there is a small screw on top of the feeder)
- When you had a lot of grinding recently, perhaps clean the feeder insides: https://ultimaker.com/en/resources/50688-clean-the-feeder
- Retighten the hotend insulator: https://ultimaker.com/en/resources/50677-retighten-the-hot-end-isolator
