The present work shows the development of both a pulse-receiver circuit and acquisition
circuit prototypes of ultrasonic signals for the measurement of thickness in oil pipelines using …

The paper presents experimental results of applying an ultrasonic monitoring system to a
real-world operating hot-water supply system. The purpose of these experiments is to …

A sensor system for the study of an oil-water flow in a pipe is proposed. The purpose is to
estimate the area fraction occupied by each fluid in a given section of the pipe, taking …

Two resonant sensor systems for fluid analysis and condition monitoring are described and
applications in industrial environment are discussed. The presented sensors are based on a …

A capacitance sensor with high sensitivity was applied to oil-gas two-phase measurement
based on a modeling and experimental studies. A model of the electric behavior of the …

In this article, the pattern variation of the wave propagation in a pipeline is studied by means
of Principal Component Analysis (PCA) and some extensions to indirectly evaluate the …

The water content in oil is closely related to the deterioration performance of an insulation
system, and accurate prediction of water content in oil is important for the stability and …

Predictive maintenance has gained wide acceptance as a cost cutting strategy in modern
industry. Condition monitoring by lubricant analysis is one of the basic tools of a predictive …

The present work contains two parts. In the first part, high temperature integrated ultrasonic
transducers (IUTs) made of thick piezoelectric composite films, were coated directly onto …

In the framework of a research project, a proprietary vibroacoustic system was desìgned for
remote real-time monitoring ofpipelines (Dalmazzone et al., 2010; Giunta and Bernasconi …
