The smart water meters that I'm familiar with operate in either the 400 or 900 Mhz range and may be in a passive mode in which they transmit only when prodded by an external source and then go back to sleep or they are transmitting 24/7. The meters vary and one has to find the white papers on them.
I know a lady who won HUD complaint against a utility which had to remove the smart water meter from her house. It was a 24/7 pulser.
I've used an analyzer on several smart water meters and could pick up the signal in the house on the room furthest away from the meter.

From what my equipment shows, smart meters attached to water lines do not raise RF levels in the home. The decibels drop with distance, like a cell phone text. Nothing to get upset about.
Smart meters attached to energized wiring is a whole different ball game due to RF traveling on energized wiring. Just think of an octopus with it's tentacles as the wiring in the walls, ceiling, and floors. The electric field that extends 6-10 feet from the wiring becomes pulsed.
Some people are forced to have them and the only option they have is to shield the opposite side of the meter and flip all breakers off, except the fridge and climate control for the home.
Do not put one of these on your own home unless the meter is facing you.

Everything can be a poison, it all depends on the dose.
