摘要

Process and device for measuring the flow velocity of a fluid utilizable even in inflammable fluids, very low flow rates, and very low pressures. Energy from the variation in fluid temperature due to internal friction is used for measurement purposes, eliminating the necessity of an exterior energy source.
