METHOD AND APPARATUS FOR THE MEASUREMENT OF THE MASS FRACTION OF WATER IN OIL-WATER MIXTURES.

摘要

An apparatus for measuring the mass fractions of water and oil in a flowing mixture of oil and water through a pipe includes a sensor portion that measures sound velocity and temperature of the flowing mixture at a first time and at a second time The apparatus includes a temperature changer in thermal communication with the flowing fluid which changes the temperature of the mixture by a measurable amount between the first time and the second time A method for measuring water mass fraction in a flowing mixture of oil and water through a pipe includes the steps of measuring sound velocity and temperature of the mixture at a first time and a second time with a sensor portion There is the step of changing the temperature of the mixture by a measurable amount with a temperature changer in thermal communication with the flowing fluid.
