[Case Study] Accurate Management of Residual Chlorine Concentration in Rinsing Water for Bottle Washing

[Case Study] Accurate Management of Residual Chlorine Concentration in Rinsing Water for Bottle Washing

Solving issues such as the inability to accurately measure chlorine concentration! Introducing a case study from a beverage manufacturer.

The beverage manufacturer was supplying sample water to the residual chlorine meter to measure the chlorine concentration of the rinsing water used for bottle washing. Currently, they are using bypass piping without a pump, but there are issues such as "the flow rate of the sample water is unstable, making it impossible to accurately measure the chlorine concentration" and "when emptying and cleaning the bottle washing tank, air and dirt get mixed into the residual chlorine meter." For solutions to the issues and requests, please download and view the PDF document. 【Customer's Issues and Requests】 ■ The flow rate of the sample water is unstable, making it impossible to accurately measure the chlorine concentration. ■ When emptying and cleaning the bottle washing tank, air and dirt get mixed into the residual chlorine meter. *For more details, please refer to the PDF document or feel free to contact us.
