It's the same -- Loudness measurements are defined precisely and every meter uses the same algorithms.
If so then how would I best connect it
It doesn't matter from an accuracy point of view as they are all straight digital feeds... so use whichever is more convenient.
However, you might want to connect it to the dedicated meter output of the monitor controller itself, so that it follows whatever you are listening to. The only downside with that is that the meter output on the Crookwood is usually analogue, so you'd need an A-D to feed the meter.
In my own setup I have an analogue BBC-style twin-twin PPM on the Crookwood monitor controller's outputs, and a DK technologies MSD600M++ digital meter across the digital record outputs of the Crookwood mastering console.
