With funding from the US Bureau of Reclamation, California – Great Basin Region (Region 10) and the California Department of Water Resources (Agreement No. 4600011908), the California Polytechnic State University, San Luis Obispo Irrigation Training & Research Center (ITRC) conducted testing on 4-inch and 10-inch spool-type magnetic flow meters ( also known as mag meters and electromagnetic flow meters) from six manufacturers (12 meters total). The testing was performed to assess the effects of various hydraulic conditions on meter accuracy.
