Liquiline System CA80FE

Summary

Product identification

The Liquiline System CA80FE is a wet-chemical analyzer designed for the near-continuous determination of iron concentration in liquid media.

Applications include:

• Monitoring residual dissolved iron after precipitation, flocculation, and filtration.
• Monitoring iron-rich process waters.
• Quality control of raw water for the food industry.

A "Cabinet, outdoor version" is available for outdoor installation.

Key Features

• Integrated controller with up to 2 measuring channels.
• Supports digital Memosens technology, allowing easy upgrade to a measuring station by connecting up to 4 Memosens sensors.
• Offers digital fieldbuses including PROFINET, PROFIBUS DP, Modbus TCP, Modbus RS485, and Ethernet IP.
• Includes an integrated web server.
• Designed for simple, tool-free maintenance.

Measuring Principle

The analyzer uses a colorimetric measuring principle. A specific color reagent is added to a prepared sample in a mixing/reaction chamber, causing a color change. A multispectral photometer measures light absorption at defined wavelengths, which is proportional to the iron concentration. A reference measurement is performed to compensate for interference.

The photometric determination of iron utilizes the Ferrozine method, reacting with iron (II) in a buffered solution. A reduction agent is included to convert Fe(III) to Fe(II) for total dissolved iron measurement. Absorption is measured at 568 nm.
