Electromagnetic flowmeter with EtherNet/IP connectivity

02 December 2011

Endress+Hauser Promag 53 flowmeter with EtherNet/IP is easily configured, monitored and diagnosed by Rockwell Automation PlantPAx process system

Endress+Hauser introduces the Promag 53 electromagnetic flowmeter with EtherNet/IP connectivity for easy integration with the Rockwell Automation PlantPAx process automation system. The Promag 53 flowmeter measures electrically conductive liquids (> 5 µS/cm) and is ideally suited for applications in food and beverage, water and wastewater, and other process industries.

The Promag 53 flowmeter features an integrated Web server that allows authorised users to remotely view flow data, conduct diagnostics, configure the flowmeter or perform process optimisation. Data can also be securely accessed by higher-level software such as ERP systems, process historians, control loop tuning programs, and asset management systems. By using EtherNet/IP, up to 10 variables can be configured, including volume flow, calculated mass flow and totalised flow for remote access.

“The Promag 53 flowmeter is engineered to integrate seamlessly with the PlantPAx process automation system via a downloadable Level 3 Add-on Profile,” says Jerry Stevens, flow product manager, Endress+Hauser. “The integration is as simple as using a USB stick and, due to its plug-and-play nature, the integration can be copied and pasted so that the initial work is done only once.

EtherNet/IP Integration

Traditionally, devices measuring and controlling process variables rely on a process instrumentation network to transfer data, while other devices within the plant work on a completely different network. By improving this complex multitier networking strategy with one standard network architecture, namely EtherNet/IP, users have better access to real-time information. This improves the ability to monitor overall performance, troubleshoot out-of-margin conditions and minimise downtime.

Companies have a growing need to capture instrumentation data and leverage it across the production enterprise,” says Steve Pulsifer, market development director, Process Business, Rockwell Automation. “With the recent EtherNet/IP investments from Endress+Hauser, coupled with the PlantPAx system enhancements, we are helping customers address this need.”

The Promag 53 flowmeter is pre-engineered to integrate seamlessly with the PlantPAx process automation system, delivering on the commitment by both companies to help users simplify their network architecture, reduce deployment time and facilitate connectivity from the instrumentation level to the business systems level. In addition to EtherNet/IP connectivity, the Promag 53 electromagnetic flowmeter has built-in connectivity to Foundation Fieldbus, Profibus, Modbus and HART.


Promag 53 is designed to measure most liquids with a minimum conductivity of 5 μS/cm, and flow rates up to 1,250 gallons per minute. A minimum conductivity of 20 μS/cm is required for measuring demineralised water. Measuring accuracy is ±0.2 percent or. ±2 millimeters per second, and repeatability is ±0.1 percent or ± 0.5 millimeters per second.

The flowmeter operates in temperatures of negative four to 140 degrees Fahrenheit (negative 20 to 60 degrees Celsius) and pressures up to 580 psi, has NEMA 4X or IP 67 protection, has FM/CSA Class I, Division two approval, fulfills EMC requirements according to IEC/EN 61326 and NAMUR NE21, conforms to the requirements of the EU and ACMA directives, and carries the CE and √ marks.
