I need a cheap flow switch that can cope with hot water; ideally something
adjustable with switch contacts, but at a push a pulse output would be OK.
Any suggestions?

Gentech FS flow switches (from Farnell - I think code 5896) does 85C
but are not adjustable (but couldn't you arrange a non-adjustable switch
in parallel with a large-bore gate valve?)
