Sometimes a common probe of an electromagnetic flowmeter cannot be chronically placed around the aorta in the dog because its weight and shape can induce vascular injuries. Moreover it may occur that the record is disturbed by the movements of the probe around the vessel. The authors describe a new type probe that is capable to produce a reliable signal of the aortic blood flow, in spite of a reduced structure of its components. Obviously, such a signal, which is greater that the one produced by a coronary blood flow probe, must be properly amplified.
