Testing of Two 30-inch Magnetic Flow Meters

With funding from the US Bureau of Reclamation, California – Great Basin Region (Region 10), the Cal Poly Irrigation Training & Research Center (ITRC) conducted flow measurement testing on two (2×) 30inch spool-type magnetic flow meters in March of 2020. Figure 1 shows the meters installed at the testing facility. The testing determined the accuracy for each test meter in a straight pipe configuration across a range of typical water velocities (0.4 to 3.8 feet per second). Testing was performed at the ITRC Water Resources Facility (WRF) using the ITRC volumetric tank as the standard flow rate measurement for all tests
