This paper outlines the basic installation and operation of magnetic inductive flow velocity sensors on large underground cooling water pipelines. Research on the effects of cathodic protection as well as into other factors that might influence the overall performance of the meter is presented in this paper. The experiments were carried out on an immersion type magnetic meter specially used for...

Abstract Corrosion damage to metal is one of the main factors that reduce safety operation pipelines. It known about 70 % pipeline failures occur due corrosion. Electrochemical protection in combination with non-metallic coatings currently method prevent aggressive effects corrosive media on The use these methods protecting pipelines has a number difficulties can be associated several protectiv...
