RE: Simple flow switch for HA feedback

["Brian Smith" <briview@xxxxxxxxxxxx>]

If it's monitoring you're after would a temperature sensor not be
cheaper
and easier retrofit.  I was planning, but confess haven't got round to yet,
to put a 1-wire sensor on the output of the boiler to monitor when it was
actually firing.

Cool thanks. It's hopefully for feedback into Comfort of the Central
Heatin=
g
status. Hoping to fit one on the output from the boiler the feeds the CH
leg. I'll take a look at the suggestions.

Paul,

Not quite sure what you want it for (irrigation, central heating etc.)
but RS have a few (!) options.

257-076 @ =A311+vat, 15mm but not compression. max temp 85 degC
256-578 @ =A324+vat for 22mm compression. max temp 70 degC
256-562 as above but 15mm compression
395-6912 @ =A3102, 1/2" BSP, max temp 80 degC

HTH,

Tim.
