Because of many advantages of ultrasonic velocity profile (UVP) -measurement, the range of industrial applications is very wide. In this chapter, flowrate measurement, food and suspension flow, and measurement around a ship are introduced as examples of applications for UVP measurement in the industrial field. In the fields of flowrate measurement, studies concerning with the accuracy of this flowrate measurement method and calibration results of an actual flow are described, including application examples such as open channel and multi-line measurement. In the field of food and suspension flow, taking advantage of its applicability to opaque fluid, a velocity measurement is performed for fluid such as tomato soup and chocolate. Using the in-line UVP + PD method, measurements of transient flow such as thermal processing and liquid displacement, which are very important in the food industry, are performed. Measurement around a ship is an application example taking advantage of the compact installation possible for an ultrasonic sensor. Ultrasonic transducers are installed on the bottom of the actual ship, and measurement examples of velocity profile and Reynolds stress are introduced.
