<p>A calorimeter using a remanence type electromagnetic flowmeter includes a core (5a, 5b) made of a semi-hard or hard magnetic material and having a property in which a remanent magnetic flux density is varied in proportion to a temperature, a coil (6a, 6b) excited intermittently to magnetize the core, a metallic pipe (l) forming a fluid path, a yoke (4a, 4b) for conducting remanent magnetic flux of said core, the yoke being fixed to the outer surface of the metallic pipe in close contact therewith without forming an air gap therebetween, and a pair of electrodes (3a, 3b) attached to the inner surface of the metallic pipe through an insulator (7a, 7b). </p> |
