I don't see any reason why you couldn't mount it vertically or need the 45's...just depends on where you're positioning the pump and the tube routing. As for the the mount arms or whatever they're called (supposedly the EU ones don't have the mount arms), I just haven't dremeled them off yet. The one will always be the test DDC, but I'm not sure on the others home yet.

I would love to see the direct comparison.
Vapor has one en route to me. I'm quite sure I have my current measurement problem worked out as well, should be able to get another round of pump testing in between radiators. I just need some slack in my day job to get back in the lab.

I was just didn't expect the pressure to scale that well, was just surprised at the curve really. Just goes to show expectations are sometimes different once you have it right in front of you.
