Abstract

Disclosed is a method for measuring the amount of liquid in a volume of gas and the associated flow rates. A method of determining the percentage of a liquid present in a volume of gas is provided. The method comprises the steps of impressing the volume of gas with ultrasonic energy, receiving the ultrasonic energy impressed upon and traversing the volume of gas, measuring the received ultrasonic energy which has traversed the volume of gas, evaluating various parameters of the measured ultrasonic energy for variations which variations are a function of the liquid fraction in the volume of gas. A method is provided for determining the flow rates associated with a liquid-gas mixture.
