Softening Control

Always easily and accurately monitor the soft water for increased hardness levels.
Softening Control is compact and very economical - for more safety of your processes without continuous maintenance.

at a glance

  • no use of indicators
  • continuous measurement as long as water flows
  • self-monitoring of the device system
  • separate alarm for water hardness and service
  • measurand output via 4 to 20 mA current loop
  • very easy installation and parameterization
  • ecological operation because there is no addition of indicators


ideal solution for

  • food industry
  • refrigeration and air conditioning
  • metallurgy


  • scale deposits
  • lamination
  • subsequent damages caused by hard water intrusions


  • mini-monitoring device for gradual water hardness threshold values of 0.25% to 10% of the input water hardness
  • most-effective alarm system for upstreamed softening systems with high safety demands on soft water quality
