Perhaps an ultrasonic flow meter? Plenty to choose from:
<https://www.google.com/search?q=ultrasonic+flow+meter&tbm=isch>
Those are some pricey meters.
I've seen ultrasonic meters used for sanitary sewer flow rates,
but usually they're mounted above a notched weir and actually
just measure the height.
Those are some pricey meters.Well, if you want cheap, there are paddle wheel flow meters <https://www.google.com/search?q=paddle+wheel+flow+meter&tbm=isch>
and turbine flow meters: <https://www.google.com/search?q=turbine+flow+meter&tbm=isch>
The problem is these require the paddle wheel or turbine to be
inserted inside the pipe, where they also partly obstruct the fluid
flow. However, they are cheaper than ultrasonic.

It's been a while since I was hands on in any mechanical rooms. But I vaguely recall we measured flow by pressure differential across an orifice. A flow meter was used for something like make-up water to a boiler, where accuracy wasn't critical and
400 boiler rooms in one location or scattered across the planet?
Drivel: I hate plumbing.
