I haven't seen it used like that, but from the context it's obvious that it means contained. It's reminiscent of 'came in at', which is a reference to a number of things registering a score. The variant 'rang' suggets that it registered a winning score -or at least, quite a good one.
PS a bell a b ell
Also the 'sweet spot' idea comes into it, as though some arbiter of smoothie goodness rings a bell to announce that you've Got It Right.
