Flow meter HDO 120 Alu/LCP

Suitable for measuring non flammable liquids. Liquid examples:   For neutral liquids,...more
non ex-proof

Suitable for measuring non flammable liquids.

Liquid examples: 
For neutral liquids, mineral oils, many acids and alkalis, paints and lacquers, etc.


  • 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 aluminium (Alu)


  • 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
