[QUOTE="NBB, post: 963356, member: 27819"] You should be able to do this as a differential pressure measurement. Make sure you use a sensor with a true analog output or you will get a ADC digital step chop in your output. Look at the output on a O-scope and you will see what I am talking about especially if you are using the digital output sensors. I did a project like this using vacuum pumps with reed valves to measure flow a while ago. When set up properly we could even see a flutter that was traced to the reed valves causing some leakage. RossKean has the right idea with a restrictor, the reservoir acts like a air capacitor. Good luck with you project. [/QUOTE]
