A magnetic flowmeter with conducting pipe wall.

In the internal pipe wall of magnetic flowmeters should be nonconductive to prevent generated electromotive force from short circuiting. Usually inside of metallic pipe is lined by insulating material. The lining material limits applicable temperature range of measured fluid and also reliability of meter. The objectives of this investigation are to eliminate the lining and to improve reliability and performance of magnetic flowmeter. In this paper theoretical analysis and experimental results are described. (from English abstract)
