The electromagnetic flow meter is used to measure the flow rate of conductive fluids and waste water. The measurement is independent of the density, viscosity, temperature and pressure. The conductivity of the fluid must be greater than 5μS/cm. The measuring tube must not be crossed by fluids carrying solid bodies of high dimension that cannot be considered suspended solids. Load losses are absent and straight stretches reduced upstream and downstream of the instrument are necessary.

Main application fields

  • Sludge and water (primary, drinking and waste) treatment
  • Control of civil and industrial wastes
  • Measurement of industrial process water: chemical, paper, tanning, pharmaceutical, food
  • Control of the chemical dosage
  • Energy industry: generation and distribution
  • Extractive industry: quarries, mines
  • Environmental protection


The electromagnetic meter must be installed so that the pipe is always completely filled with fluid. In the case of a half-empty pipe, the meter must be installed in an underground channel, or in a “goose neck”, to achieve a siphon effect. Installation may be vertical or horizontal but in the latter case, ensure that there is no deposit of material on the electrodes. Installation must take place in such a position that the piping cannot be emptied.
