Looks like the frequency of the flow meter is rather slow (~2000 Hz max).
Perhaps you could use a Windows timer to read the number of counted events by the CT every so often.
The freq would be the number of counted events since last read divided by the elapsed time since last read.

The User Guide outlines this process.
