Electromagnetic fluid velocity sensor with adjustable electrodes

摘要: An electromagnetic flowmeter includes at least one electromagnet coil arranged outside a liquid flow passage for generating an electromotive force in the flow, and pair of electrodes adjustably extending within velocity component signal. Preferably, two collinearly coils are provided externally on opposite sides passage, first set orthogonally-arranged pairs coplanar mounted adjustable probe strut that extends into flow. For greater accuracy, Hall-effect device is probe. Additional sets electrode may be secured to planes parallel set. A second collinear orthogonally relative pair, being alternately energized produce three components.
