My water line leaks. When checking the meter, I found the spinner

I wonder what causes the fluctuation, water pressure?

Have you checked all the toilets? A leaking flapper and the toilet topping off will create a cycle, but 6 secs is fast.

If a leaky flapper is the problem, the spinner should stop spinning for
a short period, assuming the filling rate is faster than leaking rate.
When the water tank is full and before the tank is filling again, the
spinner should stop.

You're assuming it's just one leak. There could be more than one, with
only one, eg toilet, cycling. You said the water line is leaking, where
is it leaking? You've found the leak, seen it or know for sure where it
is, eg underground? Isolate the rest of the system from that and see
what happens with the meter?
