Abstract

En 中文

This paper uses an experimental method to estimate the variance of flowmeter errors (random errors or Type A errors), focusing on problems of detecting defects existing in sensors even with very small magnitudes. An inexpensive and simple but accurate test bed is shown, based on the detailed experimental estimation method submitted. Some of the difficulties and shortcomings of this estimation are highlighted and a simulation and a real estimation is given. (C) 2004 Elsevier Ltd. All rights reserved.
