Global electrification and automation technology provider ABB has added Ethernet-APL (Advanced Physical Layer) connectivity to its CoriolisMaster mass flowmeter, completing the integration of the advanced communication technology across the company’s flow measurement portfolio. Ethernet-APL opens new possibilities for the collection and analysis of process data, bringing the benefits of Ethernet communications to industries such as chemical, oil & gas, power, and water.
CoriolisMaster measures mass flow, density, and temperature directly from the flowing medium, making possible highly accurate multivariable measurement in one compact device. Ethernet-APL enables much easier connection to a control system, as well as networking of the Coriolis sensors with other instrumentation in a plant. It provides a high-speed channel for process data, as well as configuration and diagnostic information. The new capabilities support real-time decision-making and predictive maintenance based on real-time data, significantly reducing errors and downtime.
Ethernet is the most common communication technology in industrial applications. However, in most process industries, its application has remained minimal due to concerns about safety, cost, and limitations on cable length, which have made it difficult to establish communication networks in large industrial facilities. These issues were addressed with the introduction of Ethernet-APL, which was created through the successful cooperation of 12 major industry suppliers of process automation, including ABB, and four international standards organizations.
Ethernet-APL offers enhanced data rates of up to 10 Mbps, a shielded two-wire connection for carrying power and data safely over the same cable, and cable lengths of up to 1,000 meters. Intrinsic safety is also fully integrated, including a profile that limits supply voltage and current to eliminate the risk of sparking, enabling Ethernet-APL to be deployed in hazardous environments. Next in ABB’s roadmap is embedding Ethernet-APL in other field technologies, such as pressure and temperature sensors.
