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

about three times faster than the slow speed. The cycle is about six

I wonder what causes the fluctuation, water pressure?

I'd look for a malfunctioning device with an automatic fill valve like
a toilet, water softener, swamp cooler, commercial ice machine, hot
water heating system or furnace humidifier.

Among the devices you mentioned, I only have toilets.

This meter is for a multi-unit building. I have shut off valves to every
unit. Yet, it still leaks. That's why I believe it is the water line
that's leaking, not the devices connected to the water line.

You shut the vales, but did that stop the flow of water? Old valve not
often use can still allow a good flow.
