The MF2 electromagnetic flow meter measures conductive liquids with no moving parts and no pressure loss. High-accuracy versions reach class 0.2, the minimum conductivity is 1.0 uS/cm, and low-, high- and mixed-frequency excitation keep readings stable even on high-concentration slurries (solids content up to 78% by mass).
Five constructions cover almost every installation: flanged (MF20), wafer (MF21), sanitary (MF22) and insertion / hot-tap insertion (MF23/MF24) for large pipes. Eleven converter self-diagnostics — empty pipe, excitation, bubbles, coating, temperature and more — flag process problems before they become downtime.
