explosion-proof
approved according to ATEX Directive 2014/34/EU, Category 2

Suitable for measuring easily flammable liquids.

Liquid examples:
For combustible mineral oils, easy flammable hydrocarbons and other chemicals in potentially explosive surroundings.

Features: 

  • For slower flow rates, high temperatures and pressures
  • Measurement according to the oval gear principle
  • For thin-bodied up to highly viscous liquids
  • Low friction resistance
  • High accuracy
  • Touch screen display with self-explanatory, multilingual user interface
  • Range of measurement from 0.26 GPM - 8 GPM (1 l/min - 30 l/min)
  • In stainless steel (SS)

Benefits:

  • Simple, modular construction
  • Easy handling
  • Precise measuring results at high repeatability
  • No recalibration required for large ranges
  • Low pressure losses in the plant
  • Comprehensive monitoring and safety functions
  • Relay module for preselection is retrofittable at any time
Explosion protection: explosion-proof
