Anyone familiar with water meters ? UPDATE

Our December waterbill was 3x normal so we asked the city to do a leak check. A guy came out and said our meter was showing .5 gals/min with our house main off . So I crawled under the house and found no leaks between the valve and the foundation where the main enters . Then I dug up the sprinkler valves and backflow ... no leak there. So we called a plumber to check for a leak between the house and street ....he opened the meter and had us shut the main off in the house again . Meter was not moving ! No leak ! Open the main and verify all faucets were off ... no movement on the meter ! The city swears the meter cannot be defective... We just got our new bill and its 2x normal !

Note : TDS Fiber has been laying lines right where our meter is and the cut our neighbors main which prompted the city to come out to repair the line .
They also replaced our meter just before the bill spiked.

Can meters give eronious eeadings ?
