Jed, a better method is to use a constant rate pump. These are
available and are very reliable and accurate. The rate is not affected
by back pressure, within reason and can be adjusted to achieve the
required delta T.

This was in Italy. But okay, that makes sense. I would use a less
sensitive flow meter. Granted, those things are ornery and often get
plugged up or broken.
The kind used in your house to bill for your water is robust but
maybe not sensitive enough. On the other hand, if they boost the
flow rate up to 4 L/min it should do. That would be fast enough to
prevent boiling, I think.
