Description

Application

The Liquiline CM444 transmitter enables the connection of up to 4 Memosens sensors, selecting from over 12 different measurement parameters. It features automatic sensor recognition, flexible expandability, and standardized spare parts across all devices in the Liquiline platform. With its comprehensive inputs, outputs, controllers, and math modules, it can also manage cleaning systems or dosing pumps. Additionally, Heartbeat Technology ensures an optimal balance between measurement point availability and maintenance costs. Liquiline CM444 is adaptable to various industries and their utilities, including:

Food & Beverage
Life Sciences
Power & Energy
Water & Wastewater
Chemicals
Marine

The transmitter supports a wide range of communication protocols and interfaces, such as:

0/4...20 mA
HART
PROFIBUS DP
Modbus RS485/RTU
Modbus TCP
EtherNet/IP
PROFINET
Webserver

For applications in hazardous environments, the device can be extended with a module featuring explosion protection approvals like IECEx, ATEX, and CSA, enabling sensor connections in such areas.

Benefits

Smart simplicity:A single controller for all parameters and applications, offering an intuitive user interface, automatic sensor recognition, and hot plug & play functionality with pre-calibrated Memosens sensors. Maximum flexibility:Universal modules for all parameters reduce spare part inventory and allow for easy, 1-click expansion to up to 8 channels at any time. Effortless system integration:A wide range of communication standards ensures compatibility with any distributed control system (DCS). Easy and safe commissioning:The ability to save configurations on an SD card allows for quick and efficient setup across multiple installations. Remote process control:An integrated web server provides operators with the ability to remotely access diagnostic data, configure settings, or review device parameters via any web browser, including on smartphones. Increased availability, reduced costs:Heartbeat Technology supports status-oriented maintenance, simplifies the verification process of the entire measurement point, and helps implement optimization measures to reduce costs.
