RE: Water flow sensors?

["Paul Gale" <groups2@xxxxxxxxxxxxxxxx>]

I've actually just ordered some of the sensors from CPC. I thought
about th=
e temp sensors but wanted a fairly quick response once the hot water had
st=
opped flowing - a temp sensor would take ages as the hot water in the pipe
=
would gradually fall.

Cheers,

Paul.
