ABB ProcessMaster and CoriolisMaster PoE flowmeters

ABB has incorporated power supply through Ethernet connectivity on board its electromagnetic flowmeter ProcessMaster and mass flowmeter CoriolisMaster.

Power over Ethernet (PoE) omits the need for a separate DC power infrastructure, providing power and communications via the same cable. This brings new agility as flowmeters can be installed wherever needed. In addition, ABB 4-wire Ethernet combines classic outputs with future communication protocols. Offering a modular design allows the combination of both worlds and helps ensure that devices are futureproof, increasing the longevity of the flowmeters.

Flowmeters with Ethernet connectivity increase simplicity, flexibility and reliability for operations in process automation, while enhancing real-time visibility of data. Previously hidden data in field devices, such as measurement values on density, conductivity or concentration of the medium, can be made available. This in turn will help users identify redundant measurement points in their plants to achieve savings along the way.

Combining 4–20 mA or digital outputs with new 1- or 2-port Ethernet helps makes classic instrumentation futureproof, with speeds of up to 100 m/s. The flowmeters use various Ethernet-based communication protocols, such as simple Modbus TCP or EtherNet/IP. This prepares them for IT/OT convergence, cloud connectivity and the requirements needed for secure and encrypted communication in the near future.

Ethernet connectivity for the ProcessMaster electromagnetic flowmeter is currently available in North America, and will be released globally later in 2021.
