Thanks for the responses.
I've looked briefly at the Beacon system. I really like the idea of having this much data in almost real time. I'm thinking it could pay for itself over time in faster leak detection and less plumber time. It looks like each meter needs an endpoint at about $80 each and there is an $.89 per meter/month connection fee. Are there setup fees?
Thanks for the advice. The problem is that my municipal meter only reads in 1000's of gallons. It's difficult to tell much in a short period of time. I may end up adding my own large meter just downstream from the city's so I can do exactly what you suggest.
You're exactly right, we have a 3" municipal meter which reports 1,000's of gallons. The city recently replaced our old meter with a new Sensus Omni meter. I was hoping that the old meter was the problem but, unfortunately, the readings are consistent. Anyway, I now have my manager take a picture of the meter with her cell phone on the city's meter reading day.
