Read about EKM a while back but don't really know anything more about them.

Elster is another company but I don't know if they make them for private consumers or just municipalities.
I could use one of these so am interested to see what your research reveals. Also on a well, tired of trudging out in the snow to read the meter in winter (have to report usage to the county).
No personal experience but this one seems to do the job: http://www.instructables.com/id/Web-Based-Water-Metering-with-ioBridge/?ALLSTEPS
One thing to check when on a well is how much flow resistance is added. You don't have a lot of pressure to begin with (at least we don't). The zero-resistance/contactless/high-flow models are better than the more intrusive (like old, old impeller) sensors.
