The objective was to analyze a recently developed flow measurement technique based on
the vibration captured by an accelerometer attached to the pipeline surface for use in the oil …

This paper presents a method for measuring flow rates in pipelines based on the flow
induced vibration principle using water as fluid, eliminating the need for interrupting the flow …

The original noninvasive method for measuring the flow rate of liquids proposed in this work
relies on the ability of the piezoelectric sensors embedded into pipes or pipe bends to detect …

This paper presents a ultrasonic-capacitive system for online analysis of the quality of fuel
oils (FO), which are widely used to produce electric energy in Thermal Power Plants (TPP) …

This work aims to evaluate the influences of the water content dissolved in crude oil and of
the meter factor on the uncertainty of the fiscal oil measuring system using ultrasonic flow …

Maintenance of oil pipelines is an issue of great concern for oil companies. Any possibility of
leakage must be detected before the leakage occurs and a preventive action should be …

The first version of the Brazilian Technical Regulation for the Measurement of Oil and
Natural Gas (RTM) was elaborated in 2000, and it was a regulatory framework for the …

Abstract Pipeline Inspection Gauges (PIGs) are widely used for monitoring and managing
pipeline integrity. During a pigging operation it is fundamental to have a continuous …

The present paper describes a procedure improving the measurement of fluid flow rates in
pipes through the measurement of vibrations. The authors show, via experimental tests for …

The present work aims at demonstrating the applicability of using tubes made of the polymer
PVDF as intrinsic flowmeters, considering the peculiar piezoelectric properties of the PVDF …
