I took over a park this month with almost 100 homes and the homes are submetered for water. I realized that the owner was fudging readings and I have over 40 meters which are not working and need to be replaced. I have seen previous discussions about using different types of meters, i.e rf, vs ones with readouts on side of home. Can anyone give advice as to what type, brand, models you would recommend for replacement and what to expect in cost? I need some help.
