If so, can anyone recommend a suitable flow cup?
Preferably easily available and cheap :-)
A known capacity bucket is by far the simplest. Larger volumes make for
somewhat more accurate measurements (i.e. a 14l bucket will be better
than a 1l jug)
Unless you are looking for accurate figures ( not sure for what purpose)
roughly timing how long it takes to fill a 2 litre jug or 10 litre
bucket ( they usually have a capacity mark on them) should provide
figures accurate enough for benchmarking or looking for problems.
I have flow figures at different outlets of between 5 and 13 seconds for
a 2 litre jug.
