Flowmeter Electromagnetic FLOWMA DN 20


WMG21 series electromagnetic flow meters are specializing in measuring conductive liquid (conductivity > 5µ/cm). These series flow meters have high applicability for low flow rate, sewage, acid and alkali liquid, low abrasive slurry. Our product have advance intellective-tech, field show abd communicator.
WMAG21 series electromagnetic flow meter.


Electromagnetic flow sensors WMAG30 are precision measuring devices, suitable for determing the flow rate of nearly any electrically conductive fluid, but also for subtances such as sludge pulp and paste. Due to the magnetic field the device can be used to measure flow rates up to 12 m/s (39.3 ft/s) and a minimum conductivity of 5µS/cm, when using a syinchronized static field. The entire measuring device comprises a flow sensor and a dedicated transmitter. Those can be delivered either separetely or as a compact unit.. The electromagnetic flow sensors WMAG30 are applied mainly in the following.

  • Water and sewage plants
  • Chemical and pharmaceutical industry
  • Food and beverage industry
  • Mining, cement and mineral mate
  • Pulp and paper industry, energy industry
  • Steel industry, public utilities

  • Offer easy installation, User-friendliness operation
  • Keep in long-time use in 150 degree hot water
  • Highly temperature sensor
  • High temperature indusrial components
  • Insulating temperature parts between sensor and converter
