November 11, 2009 - Endress+Hauser announced Promass 83 Coriolis Mass Flow Meter with EtherNet/IP connectivity. Promass 83 offers process system designers greater freedom and choice in their selection of components and architectures. EtherNet/IP is a leading Industrial Ethernet variant, and so the addition of an EtherNet/IP capability makes the Promass 83 even more attractive to machine and skid builders operating in the hybrid process/discrete control industries. A typical application for the Promass 83 would see it in a blending skid, allowing the incoming flow of a number of raw ingredients to be tightly controlled, helping to maintain the quality of the finished product. As well as measuring mass flow and density, the unit can also be used to measure viscosity.
In-line viscosity meters are often very expensive meaning that many viscosity readings are done in a lab, rather than in the line. With this device, users can measure viscosity, on-line in real time and adjust control parameters accordingly – rather than waiting for lab results. The device is also capable of measuring gasses. Promass 83 Coriolis flow meters have the ability to measure several process variables all at the same time. This opens up completely new perspectives in process control, quality assurance and plant protection.
Mass flow, density and temperature, the primary measured variables, can be used to derive other values such as volume flow, solids content, viscosity or concentrations and complex density functions. The uniform Proline transmitter concept includes:
- Modular device and operating concept resulting in a higher degree of efficiency
- Software options for viscosity and concentration measurement for extended range of application
- Diagnostic ability and data back-up for increased process quality Promass sensors are tried and tested in over 100,000 applications and offer:
- Multivariable flow measurement in compact design
- Insensitivity to vibrations thanks to balanced measuring system
- Efficient protection against forces from piping thanks to robust construction
- Easy installation without taking inlet and outlet runs into account EtherNet/IP: EtherNet/IP extends commercial off-the-shelf Ethernet to the Common Industrial Protocol (CIP) — the same upper-layer protocol and object model utilized in DeviceNet, and ControlNet.
CIP allows EtherNet/IP, ControlNet, and DeviceNet product developers, system integrators, and users to apply the same objects and profiles for plug-and-play interoperability among devices from multiple vendors and in multiple sub-nets.
Combined, DeviceNet, ControlNet, and EtherNet/IP promote transparency from sensors to the enterprise software.
Dr.
Jürgen Weinhofer, Director, Integrated Architecture, EMEA Region at Rockwell Automation, explains the user benefits from Rockwell Automation's perspective: "The EtherNet/IP interface gives users direct access to device data without addi-tional configuration or programming.
By using a standard, unmodified protocol, this data can then be shared seamlessly and very easily across the entire network.
It can then be viewed either on line-side HMIs or, via existing Ethernet networks, on computers in offices and control rooms – even remotely over the Internet."
