Re: Bathroom :Auto Filling Bath ? & TV's ?

["Mark Marooth" <MMarooth@xxxxxxx>]

Marcus,

A while ago a pal of mine did just something similar.  He put the
valves on his
existing tap pipes so that he could use a preset mixer (Electronic -
Very
envious was I) and a button which was connected to HV.  Pressing
button turned
on valves, pressing again turned off.

HV then controlled the valves.  He took a tee from one of jacuzzi jets
and
coupled this to a untrasonic pressure transducer which produced an
analogue
voltage output.  This was again wired back to HV and when the
transducer
produced the correct voltage HV turned off the valves as the correct volume
of
water was in the bath.

Took a while to callibrate but after that never failed.  When he was
game enough
he left the taps turned on and set up a timed event in HV to fill his bath
in
the morning.

I'm sure he got the transducer from RS and it was not that expensive.
