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 one (1×) 10 to 48-inch Seametrics EX21x insertion magnetic meter (“Seametrics”, “test meter”) in April 2020. Figure 1 shows the meter installed at the testing facility. The testing determined the accuracy of the test meter in a straight pipe configuration across a range of typical water velocities (0.5 to 5.8 feet per second). Testing was performed at the ITRC Water Resources Facility (WRF) using calibrated measurements from a 30-inch Krohne Enviromag 2100 (“Krohne”, “standard meter”) as the standard flow rate for all tests.1
