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.

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 …

The irrigation industry is experiencing a growth in the use of magnetic meters for measuring the flow rate and volume in irrigation pipelines. Historically, propeller meters have been the device selected by users. New legislation in California (SB7x7) will require measurement devices at key locations for irrigation water delivery. Some users are very interested in the magnetic meter for making the measurement at the turnout or farm gate. The key feature of the new meter is the ability for the device to work in less than ideal flow conditions. Electromagnetic meters have been tested by the Irrigation Training and Research …

Magnetic flow meters are used to measure the flow rate of a liquid in a closed pipeline. This type of meter is becoming increasingly popular for measurement with agriculture applications. Electromagnetic meters were tested by the Irrigation Training and Research Center in pipelines located less than the 10 diameters upstream of disturbances with good results. Results show that location guidelines for placing a magnetic meter can be decreased even for turbulent conditions. This paper will discuss how a magnetic flow meter works, advantages and disadvantages of this type of meter, test results, and new guidelines for field applications.
