Abstract
An algorithm for the construction of the magnetic system of a flowmeter of multiphase fluid media that assures its minimal weight and minimal overall dimensions is presented. The system guarantees high values of the magnetic induction in the working range of the flowmeter (0.5-1.0 T and greater) with high degree of homogeneity (less than (20-30) x [10.sup.-6]) in required volumes. Keywords: flowmeter, nuclear magnetic resonance, induction, polarization, gradient.
