🛠️ Chlorine Sensors: Industrial Applications, Online Measurement Reliability and Lifecycle Management
Chlorine measurement plays a critical role in ensuring drinking water safety, disinfection efficiency and maintaining process quality. Monitoring free chlorine, total chlorine and residual chlorine values accurately supports optimized chemical consumption, compliance with environmental regulations and safe operation.
Incorrect or unstable chlorine measurement may lead to:
insufficient disinfection
excessive chemical consumption
reduced product quality
environmental regulation violations
increased maintenance costs
unplanned shutdowns

Where are chlorine sensors used? They are applied in drinking water, wastewater treatment, food, chemical, industrial disinfection and process water applications.
What is the difference between free chlorine and total chlorine? Free chlorine indicates active disinfection capacity, while total chlorine represents the sum of free and combined chlorine.
Can sensors be monitored remotely? Yes. AMS Device Manager and Plantweb™ infrastructure enable monitoring of device status, maintenance history and diagnostic data.
