The FlowScan thread reminded me of a question I've always had, but I didn't want to hijack that thread.
Why are these sensors so expensive? OK, I get that the computers to tally up the pulses and spit out N2K require a lot of design and coding work, even thought the parts are dirt cheap.
But surely flow sensors which do nothing but send out a pulse shouldn't cost more than a few bucks.
These are the kinds of things I ponder when I'm stuck inside on a snowy day...
