In the oil industry, many applications require the measurement of more than one liquid level
interface, often in challenging environments. In this paper, a new ultrasonic-based technique …

Liquid pressure is a key parameter for detecting and judging faults in hydraulic mechanisms,
but traditional measurement methods have many deficiencies. An effective non-intrusive …

The full measuring range and real-time on-line measurement are new requirements for
measuring the water content of the crude oil in oil pipeline with the application of the water …

High-water-cut crude oil is currently the main form of underground oil in China. The high
water content and the distribution of oil and water have an important impact on the …

This paper presents an ultrasonic method to measure small concentrations of water in
lubricating oil. It uses an ultrasonic measurement cell composed by a piezoceramic emitter …

This paper presents an experimental study to investigate the suitability of thick-film ultrasonic
transducers for composition measurements in heterogeneous mixtures. Following on from …

This paper presents the design of a non-intrusive system to measure ultra-low water content
in crude oil. The system is based on a capacitance to phase angle conversion method …

This work aims to evaluate the influences of the water content dissolved in crude oil and of
the meter factor on the uncertainty of the fiscal oil measuring system using ultrasonic flow …

The water content in static crude emulsions has been extensively studied. However, the
dynamic emulsions under shear conditions have a higher stability of the water content …

This article presents the novel application of a cross-capacitive sensor for monitoring
insulation degradation of transformer oil. The condition of insulating oil is determined by …
