I used to use one for monitoring my water meters. Basically I had a Hall
effect sensor that would trigger off the same magnet that drove the meter
head, and the pulses would be accumulated by the 2423. It worked just
fine. The only thing I noticed was that I had to be sure that it was
powered before connecting it to the 1-wire bus, otherwise it would get
into some strange lockup state. I never figured it out, but it was on
UPSed power, so it didn't really matter.
Unfortunately, the city replaced my meter about two years ago, and the new
one has a much weaker magnet (not to mention a better security seal, so I
can't get the head off to slip a sensor in between...)
