ABSTRACT:
A catheter fluid-velocity flow probe is disclosed which has greater sensitivity and which dissipates less heat during operation than flow probes heretofore constructed. These significant results are achieved by providing two electromagnets in the probe to generate two separate magnetic fields. Each electrode is positioned between the poles of an electromagnet in the region of highest magnetic flux density of each electromagnet. The electromagnets are reduced in size, and a tubing may be inserted in the central portion of the probe during construction. This tubing permits the attachment of additional measuring devices to the distal end of the probe to permit multiple measurements in a fluid to be made simultaneously.
