water meters

I know about leak detectors on analog meters, but how do you detect leaks with a digital meter? I shut the house main like normal but could not figure out the digital meter?

The ones I have seen down here flash to a usage rate every few seconds. You can also take several photos of it over a period time to be sure it is not moving.

anything else?
