Measuring volume of flow?
Measuring volume of flow?
(OP)
I am looking for a way to measure volume of gas consumed by a diaphragm operated pump over a length of time. The pressure ranges from 5-85 psi and the volume can be from almost zero to roughly 22 cfm. What is a good way to measure this, as flow is not consistent I think I will probably need some type of data logging equipment. Any help would be greatly appreciated.
thank-you

RE: Measuring volume of flow?
Contact the pump vendor or go to a website that has the same or similar sized pump..
Most vendors of newer AOD pumps will give you a measure of the CFM/stroke of all of the models that they offer..
Try YAMADA pump....

RE: Measuring volume of flow?
The problem I've had with using the manufacturer's CFM/stroke data with changing demand is knowing how long you were at each demand point on the curve when the flow changes from moment to moment. Square-Edged orifice equipment would work for changing demand, but you're talking about a small tube and orifice and the corelations aren't going to be real good. Turbines would probably not spin at this demand. The pressure is probably too low for ultrasonic, but that might get you close.
