General overview of functions 

 

Softcontrol Smart is an online water hardness measuring system for the continuous monitoring of soft 
water on a connected water softening system based on cation exchangers for increased hardness con-
centrations. 
For this purpose, the device in the bypass takes minimal amounts of raw or soft water from the process 
in  a  time-controlled  or  flow-controlled  manner,  evaluates  the  residual  water  hardness  and  issues  an 
alarm if hardness breakthroughs are detected. At a fixed hardness limit of 10% based on the input wa-
ter  hardness,  the  device  triggers  an  alarm.  The  determination  of the  water  hardness  is  possible  from 
0.18 mmol/l raw water hardness. The measurements are carried out cyclically every 15  minutes in a 
flow measuring chamber, in which a selective sensor for calcium and magnesium ions is inserted pres-
sure-proof.  Alternatively,  the  measuring  cycle  can  be  controlled  by  pulses  from  a  connected  water 
meter. 
The process water samples are exchanged by automatically opening  or closing the upstream shut-off 
valves and then discarded without pressure. If hardness breakthroughs are recognized or a service case 
for the  measuring  system  is  required,  an alarm  is signaled. The  measurement functions  and  their  re-
sults are displayed with colored LEDs. The measuring system calibrates itself through automatic, cy-
clical switching from soft water to raw water.
