This lab compares this rated accuracy with a calculated accuracy based off measurements that were made. Each set of data is plotted and a linear fit of the data was used to calculate the sensors calibration function. With this function, the measurements can be corrected during data analysis. Once the lab is completed, the results were tabulated and a comparison was made between the uncertainty values. Procedure In preparation for lab, the manual for lab three should be read out of the lab manual “Measurement and Instrumentation Laboratory Manual” by John F. Maddox and Jordan C. Roberts. In the lab, a rotameter, turbine flow meter, and vortex shedding meter were setup along a piping system in series. Water was drawn from a container by a centrifugal pump at a steady rate along the system. Using a valve, the flow rate was adjusted to certain percentages of maximum flow rate. These percentages were read on the rotameter. With each percentage, data was collected from each sensor. These results are shown in Table 1 [Show More]
