They dont use a flowmeter but a volumetric counter
Ah. I confess I have never heard of one of those. Here is one with a
cross-section that looks like rotary engine:

I would describe this as a flowmeter that uses pulses from a piston and
cylinder, rather than a continuous signal from a spinning turbine. Each
pulse indicates 1 cylinder-full of liquid.
Small precision flowmeters sometimes work by adding a pulse of heat to the
passing fluid, and detecting it downstream.
They said they needed a video camera to record the flow rate at night.
That made me think it was an old fashioned analog device, such as this
one:

If this counter produces pulses, you would think they would collect that
data with a computer.
Do you happen to know what type of volumetric counter they use?
