Field of application
Liquiline System CA80FE offers precise, regulation-compliant online measurement. It supports you in controlling the iron content of drinking water, mineral water or source water for industrial processes. Like all Liquiline System analyzers, it enables plug & play of up to four Memosens sensors – minimizing the installation effort. Automatic calibration and cleaning and the low reagent consumption reduce operating costs while advanced diagnostics with remote access ensure process safety.
Liquiline System CA80FE monitors:
Iron content in drinking water and mineral water
Residual iron after precipitation, flocculation and filtration processes
Process water containing diluted iron
Benefits
Compliance with standard ferrozine method ensures direct comparability to lab measurements
Supports predictive maintenance by advanced diagnostics
Reduced operating costs through automatic calibration and cleaning as well as low reagent consumption
Easy upgrade of functionality - even to a complete measuring station - simply by adding modules and connecting Memosens sensors.
Comfortable remote access via integrated web server
Seamless integration into process control systems thanks to digital field busses such as Modbus, PROFIBUS or EtherNet/IP
