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

This paper presents a microcomputer-based method that can be used to categorize mineral
deposits in petroleum pipelines using ultrasonic measurements. The system was developed …

This paper presents the improvement of an ultrasonic pulse generator for a pipeline
inspection gauge (PIG), which uses 64 transducers for inspecting distances up to 100 km …

eni SpA has promoted and supported a research project (DIONISIO) for the design of a
proprietary pipeline monitoring system, exploiting negative pressure waves and statistical …

To carry out the troubleshooting of hydraulic systems, pressure readings are often required
to be taken at a number of temporary locations where the conventional instruments usually …

Measurement of water concentration of oil–water mixtures in a pipeline is important in the oil
industry. Capacitance, γ-ray and ultrasonic techniques have been developed for the …

There is increasing demand for the on-board diagnosis of lubricating oils. In this research,
we consider various sensor principles for on-board diagnosis of the thermal aging of engine …

Ultrasonic sensing uses the time of flight (TOF) of an ultrasonic wave and its dependency on
the flow rate of the medium to measure and calculate volume flow, using the difference in the …

This paper describes an 8-path ultrasonic flow meter, with emphasis on how this meter can
be used as a master meter with traceability to appropriate standards. In particular the paper …

Real time monitoring of a fluid transportation system is still a challenging matter, due to the
complexity of the asset and a continuous demand of sustainability. The current frontier is a re …
