No.
There are industrial flow meter solutions (doppler, transit-time,
mechanical, etc).
There is no demand for a home version.
I'm some-what inclined to do home automation, and the only thing I would
do along those lines would be to install a mechanical flow meter where
my main water line enters the house. I'd only be interested in total
water flow, not the flow to individual branches (bathrooms, sinks,
toilets, etc). I'd probably install a pressure and temperature sensor
at my main water supply point first before I'd ever install a flow
sensor.
Mechanical flow meters are also known as turbines and rotometers.
Here's some examples:

I've worked with doppler and transit-time flow meters used to measure
blood flow in biomedical applications, so I know how they work and why
they are the preferred tool to measure blood flow in arteries in living
subjects. But for home water consumption, I wouldn't go with
ultrasonic.
My utility provided one of those for me.
