This work deals with a transmission-reception ultrasonic technique for the real-time
estimation of the water content in water-in-crude oil emulsions. The working principle is the …

The extraction process of crude oil requires addition of water, resulting in complex
emulsions, in which the phases must be separated before the petrochemical processing …

This work shows the application of an ultrasonic multiple-scattering sensor for monitoring
water-in-petroleum emulsions. The sensor consists of a commercial ultrasonic transducer …

This work proposes the slope of the phase spectrum as a signal processing parameter for
the ultrasonic monitoring of the water content of water-in-crude oil emulsions. Experimental …

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 …

Recent research on the suitability of permittivity and microacoustic viscosity sensors for the
monitoring of water-in-oil emulsions showed that permittivity sensors could be used to …

This work reports the experiments carried out with an adjustable measuring cell for
ultrasonic characterization of water-in-crude oil emulsions. The cell prototype was designed …

For many applications, the detection of water content in an oily base liquid is of crucial
importance. Typical examples are automotive oils, eg engine and transmission oils, where …

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

In order to have on-line measurement of water content in heavy fuel oil (HFO), the so-called
water-cut meters are used. Typically, measurements performed by these devices are based …
