Does anyone know where to get a water flow meter that will close or open
a
switch when water is flowing? I have an AC unit that uses water to cool
itself and it produces 110 deg water if you reduce the flow enough. I'm
trying to build a setup that will switch between the on demand hot water
heater and the AC unit for the house. The major difficulty is
determining if
there is water flow to the hot water lines in the hosue..

Thanks,

Jacuzzi heater safety switch is a NO switch that closes when water flows
(i.e. pump is on and working.)

Thanks! I'll look into that. This may be exactly what I need. For use with
hot water, and flow switch.

My (very typical) automatic shower pump has a flow operated switch in both
the hot and cold sides, to start it up as soon as water flows as a result of
opening the water valve. It's based on a small magnet that moves up against
gravity in the water flow, and closes a reed switch. When the valve is shut
and water flow ceases, it sinks back down, and the reed switch opens. If you
know any plumbers, they're sure to have an old pump that they have changed
lying around, that you could cull the switch assembly from.
