Metron Water Meters, have you heard of them or used them?

[Vera Herlihy]

We have a duplex. The water is not separated so we have to pay for it. I was told that Metron is a company that can put meters on the line without having to redo everything. Has anyone used them and if so what's your opinon? Did it work and is it worth the cost? 

In Pitts, it's illegal to bill back unless you have a metering system. 

Suggestions?
