You need a flow meter to do this right. In the 18-hour test they reportedly
did use a flow meter. I asked them what make and model. They never responded
so I did not include this detail in my description.
Flow meters have to be reliable: don't we all trust the gas pump? ... do we? ;-)
Sure, the ones used for gas pumps and to water meters are especially
reliable. In a test of several kilowatts you can use one of the latter
and it should not be problem. The type I referred to as being a "pain in
the butt" are laboratory grade high precision ones that typically
measure less than 1 L/m. They produce good data but they frequently clog
up and you have to monitor them.
I may have uploaded this before, but here is a handy guide to laboratory
grade flowmeters:
