Endress+Hauser introduces the Liquiline System CA80AM ammonium analyzer for monitoring critical control points in water and resource reclamation facilities. The Liquiline CA80AM colorimetric analyzer reportedly provides accurate and reliable measurements by using the standard indophenol blue method, which is compliant to ISO 7150-1, DIN 38406-5 and GB 7481-87 standards. The CA80AM analyzer also provides data storage and retrieval using on-board logbooks to allow continuous documentation for reporting to regulatory agencies.
Multiple communications methods—including EtherNet/IP, Modbus, Ethernet and an integrated web server—allow the analyzer to be integrated into any control system. The integrated web server allows a user to remotely analyze process disturbances through any web browser. Three sample preparation systems offer various filtering methods based on the characteristics of the sample, and include automatic backwash systems to keep the filters clean. All sample preparations are digitally controlled by the Liquiline CA80AM analyzer to guarantee synchronization of the measuring point, according to the company. A CA80AM analyzer can have up to two channels of input to further reduce the cost of measurement across the water reclamation facility.
The CA80AM has precise, positive displacement dispensers to minimize the amount of reagent used for analysis, and it can be fitted with a smart, energy-efficient Peltier cooling module for the primary reagent. The cooler is controlled automatically via the analyzer’s electronics, and does not require maintenance. Reagents can last for up to 12 weeks. Integrated automatic cleaning and calibration functions enable the analyzer and its sample preparation to work without manual intervention for extended periods of time. If an issue with the system arises, the analyzer’s advanced diagnostics and remote access quickly guide operations personnel to resolution.
The Liquiline electronics platform in the analyzer creates a complete measuring system by connecting up to four analytical sensors via the digital Memosens protocol. Memosens sensors from Endress+Hauser include dissolved oxygen, total suspended solids, chlorine, pH and ORP. When installed in an aeration basin and combined with suitable Memosens dissolved oxygen and solids sensors, the CA80AM analyzer provides the required measurements for precise, load-dependent control of oxygen blowers with just one device, according to the company.
