Field of application
The Liquiline CM444 transmitter allows you to connect up to 4 Memosens sensors of your choice from over 12 measurement parameters. It offers automatic sensor recognition, flexible expandability, and standardized spare parts with all other devices of the Liquiline platform. With its inputs, outputs, controllers, and math modules, you can even control cleaning systems or dosing pumps. Heartbeat Technology helps you find the ideal balance between measuring point availability and maintenance costs.
Liquiline CM444 is suitable for all industries and their utilities, such as:
-
Food & Beverages
-
Life Sciences
-
Power & Energy
-
Water, Wastewater & Waste
-
Chemicals
-
Marine
It features the following communication protocols and interfaces:
-
0/4…20 mA
-
