How we can find the total number of faces of our meta-particles?

I’m asking to learn how i can find the total number of the faces/edges/vertices of my meta-particles (such like meta-balls or fluid simulation particles)

I need to know the total number of the faces of my particles that will run in my scene.
In each frame 10-80 new faces are created and so it will be hard to count them in a animation of 300 frames.

Thanks!

If there is not any way to do that with just blender alone then is there any plugin that counts the total face number of meta-particles? (or fluid simulation particles)
I want to find the number of all face of my meta-particles.

Faces that have been counted must not recounted. (i want no double-count)
