An ultrasonic measurement technique for determining water layer thickness is presented.  The technique can obtain information of the water layer thickness in a tube in the form of a horizontal flow pattern profile through the used of a correct quantitative method.  The main objective of the present work is to measure the water layer thickness of the flow using an ultrasonic measurement system.  Ultrasonic measurement techniques of water layer thickness are produced to measure the variations in water layer thickness in the horizontal stratified flow and vertical annular flow regimes.
