A new ultrasonic-based device for accurate measurement of oil, emulsion, and water levels in oil tanks

In the oil industry, many applications require the measurement of more than one liquid level interface, often in challenging, environments. In this paper, an ultrasonic technique has been developed to examine the propagation of ultrasonic waves in the oil, water, and mixed oil-water liquids. Preliminary experiments have been conducted on the device. In this paper, the design and operating parameters of this device are discussed and evidence for the satisfactory performance is given.
