Have a well with an indoor water meter. County is requiring the ability to read on outside of home. Meter body marked Precision 5/8"PMM, with meter marked Invensys PMM. It has a rotating clock type pointer and then a analog display showing gallons used.

Can anyone suggest a retrofit that could go on the meter with a display that I could mount outside??? Only about 1' to outside wall, so hard wired is preferable.
