Proline 300/500 – Flow measuring technology for the future

For 45 years, Endress+Hauser has been offering one of the most comprehensive product ranges worldwide for flow measurement of liquids, gases and steam. The Proline device family has contributed significantly to this success with unique innovations to ensure highest process and product quality. The Proline 300/500 transmitter family combines Proline sensors, which have proved themselves with state-of-the-art transmitter technology.

Proline 300/500 allows universal flow metering in all applications in the process industry – from quantity measurement and process monitoring right up to custody transfer applications. Proline also provides a view into the process, ensuring that plant operators receive a wealth of important diagnostic and process data. Users benefit from this in many different ways: through optimal process monitoring, fewer periods of downtime, and therefore a more efficient process control.

Proline 300/500 transmitters can be freely combined with any of the Coriolis, electromagnetic, Ultrasonic and thermal sensors, so that users can easily operate the devices without having to get used to different interfaces. Several process variables can be measured simultaneously depending on the corresponding measuring principle and sensor. Each device is checked using accredited and traceable calibration facilities (ISO/IEC 17025). This is unparalleled around the globe.

Proline 300/500 supplies the customer with a maximum amount of process information. It is not only possible to retrieve device, diagnostics, service or process data in the control room, but also on site thanks to the built-in Ethernet or WLAN that allow for direct connection via web server. The web server is an innovation that simplifies service of a device and thus ensures efficient maintenance.

A further highlight is Heartbeat Technology. Integrated into all Proline devices, this checking function enables permanent self-diagnosis, along with an attested and traceable verification during operation. The operator does not need to be present in the field: Verification can be started at any time via all available interfaces. This makes it possible, for example, to extend application-specific calibration intervals, thus saving time and money.

Proline 300/500 has a unique range of signal outputs and protocols: HART, PROFINET, EtherNet/IP, Modbus RS485, PROFIBUS and FOUNDATION fieldbus. This ensures that all Endress+Hauser flowmeters can be seamlessly integrated into existing automation systems. Thanks to the transparent flow of diagnostics and measurement data – from the sensor to the process control system – unimagined possibilities are now becoming reality, ensuring safe, efficient and comprehensive process control.
