The presence of water in lubricating oil is destructive even in very small quantities. The
ultrasonic measurement is an alternative method to find a solutions for detecting and …

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 …

Liaohe Oil Field is a low permeability reservoir, formation oil poor, so far taken the field is
ongoing recovery process, but the time of really pumping oil doesn't account for 20% of …

In this paper, we propose the new detection system for discriminating water in oil. The
detection method adopts the difference in each temperature characteristic of propagation …

This paper presents an investigation of the capability of the acoustic emission (AE)
technique in the processes of monitoring and detecting the variation of engine oil's viscosity …

In this paper a ultrasonic oil level meter for measuring oil levels of vehicle transmissions is
designed and its effectiveness is shown by experiments. On a FPGA (Field Programmable …

A prototype model of an Acoustic Engine Oil Quality (AEOQ) sensor is presented. The AEOQ
sensor utilizes changes in oil viscosity as an indicator of the oil quality. The supporting …

This paper presents an empirical method for measuring the viscosity of mineral oil. In a built-
in pipeline application, conventional ultrasonic methods using shear reflectance or …

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 …

This paper presents an investigation into the application of an ultrasonic tomography system
to determine the composition of water and oil flow. There are three modes of the ultrasonic …
