Water flow sensors?

["Paul Gale" <groups2@xxxxxxxxxxxxxxxx>]

Can anyone recommend a cost effective DHW water flow sensor? i.e. not
a =A3=
100 each RS part! ;)

As my replacement heating system is going in, I want to fit 3 x water flow
=
sensors in 15mm plastic (JG speedfit) to the supplies to the hot feed on 3
=
x showers. The contacts need to be simple no-volt contacts that will then
f=
eed into HomeVision. This will allow me to do some clever stuff like
turnin=
g on fans and electric mirror heaters etc.

Thanks,

Paul.
