Flow 33 EX Inductive Flow Meter

The Flow 33 Ex is an inductive flow meter from Comac Cal. Produced without a display unit this hard-wearing flow meter is an ideal solution for technological processes. This includes chemical or mining industries with demanding requirements and possible explosion atmosphere hazards.

The flow meter is manufactured using structural steel with a polyurethane coating. It is completely corrosion-proof, meaning the meter can be used in even the hardest of environments. This also gives the unit a long service life under heavy-duty conditions and boasts superior control systems for easy usability.

Features of the FLOW 33 EX:

  • ATEX certification for explosive atmosphere
  • The status is indicated by LEDs.
  • Possibility of compact full corrosion-proof construction
  • Rock steady construction
  • High variability of mechanical connection.
  • Wide range of materials for liners and electrodes
  • Easy and maintenance-free attendance
