F-3000 Series electromagnetic flowmeters from Onicon Inc., Clearwater, FL, use a velocity measurement principle based on Faraday's Law and are available in 19 sizes from 1 in. to 42 in. pipe diameters. The flowmeters are factory configured and feature accuracy to ?0.2% of rate from 3–33 fps; flow ranges from 2.37–137,361 gpm; 230 psi standard pressure; bidirectional flow measurement; volumetric flow measurement independent of fluid density, viscosity, and temperature; and no moving parts. Each sensor is wet calibrated. Typical applications include monitoring cooling water, heating water, condenser water, and domestic water.
