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 …

Problems of detection and quantification of scale deposits in petroleum pipelines are
discussed. Solutions based on novel ultrasonic techniques to extract characteristic features …

This paper presents a novel approach to material characterisation in situ using ultrasound. A
major problem associated with the use of ultrasound in such measurement is the distortion …

Development of time and frequency domain feature extraction techniques and wavelet
transform methods to detect scale deposits in petroleum pipelines from top-side ultrasonic …

Scale formation in petroleum pipelines causes progressive flow reductions, leading to large
production losses and operating costs. The composition and thickness of the scale deposits …

This chapter highlights a representative example of overall capabilities of ultrasonic wall
thickness monitoring sensors. Ultrasonic thickness gauging is one of the most commonly …

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 …

Automated inspection systems are important for maintenance and rehabilitation of pipeline
systems in North America given their budgetary constraints, demand on providing quality …

Recent advances in electronics, transducers, ultrasonic and computing technologies, have
led to the development of inspection systems for underground facilities such as water lines …

The design of non-destructive testing systems for fault detection in long and not accessible
pipelines is an actual task in the industrial and civil environment. At this purpose the …
