When the slurry is just a mixture of water and mud, use polychloroprene rubber (CR) lining and SS316 electrodes; if there are sand and stone particles in the slurry , it is recommended to use a wear-resistant polyurethane (PU) lining and tungsten carbide electrodes for measuring.There are no moving parts in the pipeline, no flow blocking parts, that is the important reasons for choosing electromagnetic flow meter to measure slurries and mud.
Magnetic flow sensor for slurry , in addition to measuring the volume flow of general conductive liquids, the measurement of the volume flow of uniform liquid-solid two-phase suspension liquids such as mud, mineral pulp and paper pulp which has been recognized by the industry.
There are no moving parts in the pipeline, no flow blocking parts, this is also one of the important reasons for choosing electromagnetic flow sensor to measure slurries and mud. When the slurry is just a mixture of water and mud, use polychloroprene rubber (CR) lining and SS316 electrodes; if there are sand and stone particles in the slurry , it is recommended to use a wear-resistant polyurethane (PU) lining and tungsten carbide electrodes for model selection.

2) How to Select the Electrode Material of Magnetic flow meter ?
3)Can magnetic flow sensor measure te high temperature fluids ?
Because the insulating lining material of the measuring tube is limited by temperature, industrial electromagnetic flow sensor cannot measure high temperature and high pressure fluid; magnetic flow sensor is easily affected by external electromagnetic interference as well.
