Thank you for your comments. I also used to think that if the salt content of the source and softened water does not change, then the electrical conductivity does not change either. But it turned out that the electrical conductivity of softened water increases. And the more sulfate in the water, the greater the difference in the value of electrical conductivity is. More detail - https://tiwater.info/en/the-method-of-controlling-the-process-of-ion-exchange-water-softening/ This method is not a direct alternative to the colorimetric method. This is just a variant of operational continuous monitoring. Monitoring can be remote. When the water is fully softened, the Langelier index will be negative. The water will be corrosive. If water is used for water supply, it is necessary to make a mixture of softened and source water.
