I really like the idea of an electronic water level
indicator. My track is ground level, if I could adapt
an electronic indicator to my FrankS and Ruby that
would turn on when the water reaches a predetermined
level then I would not have to stand on my head to
look at a site glass or stop every 15 minutes to add
water to the boiler. My thought is that if something
could be adapted through the pressure relief fitting
then an additional hole would not have to be drilled
and tapped into the boiler.
