摘要：
Various flowmeters (10, 70, 110, 120) each have an ESR sensor (13, 73, 112, 121) for measuring the crude oil fraction and/or velocity of a fluid containing crude oil. In combination with an NMR sensor or other sensors, a complete set of flow fraction, flow velocity, and flow rate measurements can be obtained for multiphase fluids containing gas, oil, water or any combination thereof.
