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