Ceramic Magnetic flow meter

The RBEF Ceramic magnetic flow meters have ceramic liners in place of the typical elastomer liners commonly used in magnetic flow meters. The ceramic measuring tubes feature an outstanding combination of material properties including surface hardness and quality, mechanical stability and resistance to corrosion and temperature change. Benefits for the operator include ultimate accuracy and long-term stability as well as vacuum resistance and diffusion resistance. The versatile profile combined with the high accuracy, these flow meters are used in all sectors of industry.
