Capacitive Phase Shift Detection for Measuring Water Holdup in Horizontal Oil–Water Two-Phase Flow
In this paper, a phase shift detection system of flow impedance is designed based on a concave capacitance sensor (CCS). The flow impedance of oil–water stratified flow is investigated by establishing an equivalent circuit model and a finite ...

An Ultrasonic Sensor for Distance Measurement in Automotive Applications [PDF]
This paper describes an ultrasonic sensor that is able to measure the distance from the ground of selected points of a motor vehicle. The sensor is based on the measurement of the time of flight of an ultrasonic pulse, which is reflected by the ground. A

Evaluation of Coating Thickness Using Lift-Off Insensitivity of Eddy Current Sensor
Defect detection in ferromagnetic substrates is often hampered by nonmagnetic coating thickness variation when using conventional eddy current testing technique. The lift-off distance between the sample and the sensor is one of the main obstacles for the

Estimation of temperature inside unsteady cavitation in high-temperature water
Cavitation is a phenomenon that degrades the performance of fluid machinery, whereas the thermodynamic self-suppression effect of cavitation is prominent in pumps transporting cryogenic fluids because the effect suppresses cavity development.
