Liquiline transmitters with Heartbeat Technology offer status-oriented maintenance and easy verification of the measuring point and help you to carry out optimization measures.

The transmitter's modular design allows you to easily add functionality at any time. ©Endress+Hauser

Stay flexible with the Liquiline CM444 transmitter: its modular design allows you to easily add functionality at any time (e.g. digital fieldbuses, number of channels, relays, etc.).

Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
