The objective of my question is .. to desighn an aoutamatic system with minimum human error to find the flow rate of a gas .. which in turn will be used to calliberate the mass flow controller.
The mechanical way could be to see the initial and final volume of the flow of a soap bubble ,which the gas causes to generate and
note the time taken to do this. This accounts for
human error, hence we need to design an automated system where the flow velocity is auotomatically given.
I will be greatful if you could anser the querry
as soon as possible.
Thanking you in advance.
