  • Fit any water softener system

  • Self diagnostic of complete system
  • Signal outputs for remote information

Control and monitoring of softened water quality, by comparison of waters from softener inlet and outlet.


BAMOSOFT Control, monitors safely the quality of softened water. It emits a light alarm as soon as the hardness of outlet water is near or above the threshold.
Example :
Raw water (tap water): hardness of 300 ppm CaCO₃ Threshold is set at 0.25 %: for alarming when hardness of softened water is above 0.25 % of raw water hardness. It means that an alarm occurs when softened water hardness is over 0.75 ppm of CaCO₃.

BAMOSOFT Control also delivers a 4-20 mA signal which represents the percentage of residual hardness in the softened water, in comparison to raw water hardness.
Raw water hardness (tap water) is 300 ppm CaCO₃. Output signal 4-20 mA is set on the scale 0 ... 2 %. The value 20 mA will represent 2% of raw water hardness, in this case: 6 ppm CaCO₃.


BAMOSOFT Control comprises two solenoid valves that successively pass raw water and then softened water on a specific Ca⁺⁺ /Mg⁺⁺ electrode. With its hardware, the analyser contemplates the ionic activities, compares data and proceed to check the system, less or more frequently. The controller delivers information: normal operation, alarm, faulty solenoid valve, brine leakage, etc. Water samples are rejected to drain (no pressure).

After start up, once measurements are stabilized, BAMOSOFT triggers a sampling routine each 15 minutes. It is possible to trigger sampling by an external signal (counter with pulse, external contact).
