Average velocity within a simple region

Massive success, in my terms, since my last contact and thank you!!

I now have a model that has given me great calculated average velocity results from planes in the Supply (Inlet) Port, to the left of the device. But I’m having great dissagreement with axial slices. Therse are the slices I am using

And these are the ones in question

I get zero or positive, left to right, velocities from my plane calculations in the left hand Supply (inlet) port but these scaled velovity images are all negative, right to left. I think this is something related to velocity scaling so could you please direct me to some help in using the scaling option.

Here is also a brief PDF note that I’ve posted to LinkedIn that I hope may explain my velocity sclaing concerns.

Many thanks again
