Failure Modes Analysis of Electromagnetic Flowmeter Based on Grey Relational Analysis

Abstract

Firstly this paper introduces gray relation analysis, and then it draws various reasons of electromagnetic flowmeter malfunction in combination with data provided by one company. And the paper calculates the probabilities of the various reasons adopting classical statistics, and equalizes these failure rate data to get sequence difference, and then obtains grey incidence coefficient and correlation degree. Then the paper sorts these correlation degrees to confirm the influence degree of the failure modes. Finally, the bleaching information required is obtained.
