Introducing the Liquiline CM44P Analytical Transmitter

Simplifying monitoring of chromatography, fermentation, phase separation and filtration

Endress+Hauser introduces the Liquiline CM44P multichannel analyzer transmitter that accepts up to 16 parameters from analytical sensors and transmits them via 4-20mA HART, Profibus, Modbus or EtherNet/IP. The CM44P accepts inputs from up to two process photometers and four analytical sensors simultaneously. Sensor types include pH, ORP, conductivity, oxygen, nitrate, turbidity, free chlorine and ion selective sensors.


  • Intelligent design: One controller for all parameters including process photometers
  • Cost-saving and comfortable set-up of measuring points: Combine up to two process photometers and four Memosens sensors for a perfect fit to your application
  • Easy to operate and calibrate thanks to intuitive user interface and menu guidance
  • Seamless integration into distributed control systems thanks to digital fieldbus protocols such as Modbus, PROFIBUS and EtherNet/IP
  • Process control and safety: Integrated web server that allows the operator to remotely view diagnostic data, perform configurations, or access device parameters in any web browser – even via Smartphone
  • Available as DIN-rail version for applications with limited mounting space – perfect for system integrators and skids

Multiparameter Monitoring

Chromatography, fermentation, filtration and phase separation require monitoring of multiple parameters. In chromatography, for example, the combination of a UV process photometer and pH, temperature and conductivity sensor inputs ensures accurate detection of the target product. It also verifies buffer quality in the column is correct, leading to optimum product yield. The CM44P detects the transition from product to cleaning phase, allowing optimization of cleaning and flushing cycles.

Standardized digital platform

The CM44P interfaces to all Memosens sensors from Endress+Hauser and other vendors. Memosens is an international standard, with all sensor-related data stored directly in the sensor head. The CM44P can access this data for analysis, mathematical calculations and diagnostic purposes, and transmit it via various interfaces
