How does it know if some is home?

I believe it was on this forum, many months ago, that I read
a reference to a device that could be installed in one's
water line so that if a pipe burst when no one was at home
the water would shut off automatically. I assume the
shut-off would be triggered by a sudden heavy and sustained
(5 minutes?) increase in water flow.

What are these called? How do they work? I'd like to do a
little research on the net and locally, but I have no idea
of the proper term.

The only time a pipe burst I was home and able to get the
main water valve shut off very quickly. I may not be so
lucky next time.

Any help appreciated.
