This is a crock, pure and simple. The meter could increased to infinity, and it wouldn't make up for the hundreds of feet of 3/4-inch pipe already in place.

Compared to pipes in a system, a water meter has no appreciable flow limit, so long as it's identical in size to the plumbing going in and out. A 3/4-inch meter is rated for a 30 gpm flow. There's no way the sprinkler system is using 30 gpm, or even half that.

All you get from installing a meter larger than the plumbing it's set in, is a few psi in increased pressure. Changing the 3/4 to a 1 gives you less than a 5 psi increase, since the 3/4 meter didn't represent a significant pressure loss in the first place.
He asked if he "could have" "before he installed the hundreds of feet of 3/4". I know I said meter I guess I meant water service. The meter is sized with the service. Who would install a 3/4" yoke and slap in a 1" meter....

See .... already installed, second guessing question .... no "before" anything.
