Flow rate is varied by changing the power setting on the fan powerstat.
Two curves showing flow rate vs. fan power are to be generated, one for each type of meter. One important objective is to make the flow measurements while only minimally disturbing the flow. With data collected from the experiment, you will have the opportunity to compare the performance of the two meters. Fan flow rate can be changed by using the powerstat on the power supply. It is up to the students doing the lab to come up with a test procedure to satisfy the lab requirements.
