Power over Ethernet flowmeters

ABB Measurement and Analytics has introduced the first Power over Ethernet flowmeters, incorporating power supply through Ethernet connectivity on board the latest edition of its electromagnetic flowmeter ProcessMaster* and mass flowmeter CoriolisMaster. This opens a new chapter in instrumentation and industrial communication. Power over Ethernet (PoE) offers a number of benefits for process engineers, as it obviates the need for a separate dc power infrastructure by providing power and communications via the same cable. This brings new agility for process engineering as flowmeters can be installed wherever needed. In addition, ABB 4-wire Ethernet combines standard outputs with future communication protocols, providing for greater longevity of the flowmeters. Furthermore, flowmeters with Ethernet connectivity increase simplicity, flexibility and reliability in operations in process automation, as well as 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 unlocked. This in turn will help customers across all industries identify redundant measurement points in their plants to achieve savings. “ProcessMaster and CoriolisMaster with Ethernet will support our customers’ digital journey towards Industry 4.0 and smart cities,” says Frank Frenzel, Global Product Line Manager Process Flowmeters. “Ethernet is the leading communications technology. By incorporating it into the ABB flowmeters, we can help more customers reduce the complexity of their operations and lower Bürkert Fluid Control Systems’ proven FLOWave flow- meters are now approved for use in potentially explosive atmospheres. Providing hygienic measurement without media-contacting sensor elements in the tube, the flow- meters can therefore be used in Ex zones with flammable solvents such as alcohols, for the production of pharma- ceutical products, spirits, semiconductors, paints and varnishes, for example. For a reliable process, quality and production guide- lines must be observed and production parameters doc- umented, even with frequent product changes. Bürkert’s FLOWave flowmeter Type 8098, now also available as an ATEX-certified version up to Ex zone 2, is a compact and lightweight device. It measures the volume flow independently of the medium’s conductivity and is, therefore, also suitable for measuring ultrapure water and alcohols. The flow sensor also measures the temperature and the density factor and can quickly and reliably detect any media change, for example, during SAW flowmeter with explosion protection approval

Flowmeters with Ethernet connectivity provide for greater flexibility in process automation as well as enhancing real-time visibility of data. costs of infrastructure in more plants around the world – safely and remotely.” An integrated secure webserver based on the ABB Ability™ Cyber Security framework ensures robust and secure operations that offer instrumentation engineers support during commissioning and troubleshooting. It also provides access to configuration, diagnostics and measurement data through a built-in QR code. This allows verification of all parts of the flowmeter and provides insights into its operating condition with automatically generated reports. Combining 4...20 mA or digital outputs with new 1- or 2-port Ethernet makes traditional instrumentation future- proof, with speeds of up to 100 Mbit/s. The flowmeters use various Ethernet-based communication protocols, such as simple Modbus TCP or high performance EtherNet/IP. This also provides for IT/OT convergence, cloud connectivity and secure and encrypted communication. *Ethernet connectivity for the electromagnetic flowmeter ProcessMaster is currently available only in North America. It will be released globally later in 2021.

rinsing processes. It supports Bürkert’s EDIP (Efficient Device Integration Platform) for easy digital integration into the control system. The flowmeter operates using the SAW (surface acoustic waves) method. With this measuring principle, there are no dead legs or sensor elements in the measuring tube. The CIP/SIP-capable flowmeters can thus be cleaned as easily as normal pipelines, which reduces operating costs. All media-contacting parts are made of stainless steel. Hence the sensors meet the highest hygiene standards and facilitate the validation of production and cleaning processes. For more information contact Bürkert Fluid Control Systems.
