Sierra's MultiTrak™ 670S is an advanced state-of-the-art instrument for measuring mass flow rates in very large ducts or stacks that have non-uniform velocity profiles, high turn-down requirements, dirty gas streams, wide temperature ranges and fast velocity and temperature changes. The MultiTrak™ dynamically compensates for changes in the flow profile by using up to four independent mass flow sensing points to measure the instantaneous average gas mass flow velocity. The MultiTrak™ is commonly used in petrochemical refining, coal-fired electric power generation, steel manufacturing and many other industrial processes that face the challenge of accurate and repeatable gas mass flow measurement in very large pipes or ducts.

An innovative, versatile and user-friendly microprocessor-based Human Machine Interface (HMI) controls all functions of the MultiTrak™system. The HMI is used to collect, visualize and store flow data, as well as set up the individual sensor points, thus allowing the entire system to be easily configured in the field. The MultiTrak™ HMI integrates the functions of flow measurement, flow-range adjustment, field validation and diagnostics, and displays mass flow rate and totalized flow, as well as other configuration variables. All of this data is easily programmable from the HMI's easy-to-use touch screen.

Unlike single probe insertion sensors where each sensor point is on the same insertion probe, each MultiTrak™ sensor point is completely independent of the others, allowing for easy field swap-out or cleaning of individual transmitters.

• The standard 670S system consists of up to four sensing points linked via Modbus, one control box with touch-screen HMI and a 4-20mA output module with the associated cables (power, 4-20mA output cable for daisy-chaining all sensing points).
• Innovative and user-friendly HMI offers advances over industry-standard collector boxes and allows users to:
• Average the flow of 4 meters
• Convert flow units
• Set up the density of the gas for mass flow measurement
• Easily configure the individual meters
• Set up alarms
• Unique multiple transmitter approach allows individual points to be removed for service or repair without shutting down the system
• Direct mass flow monitoring eliminates the need for separate temperature and pressure inputs
• Accuracy +/- 1 % of reading plus 0.5% of full scale
• Patented Dry-Sense™ technology eliminates sensor drift
• State-of-the-art calibration facility ensures a highly accurate calibration that matches the application
• High temperature option to 750ºF (400ºC) available
• Low pressure hot taps available

The Model 5700 transmitter delivers the best in measurement technology and offers unparalleled support -- providing you with total measurement confidence, valuable process insight and improved productivity through simplified solutions.

With the 5700, you are no longer confined to one variable. You can now get mass flow, volume, temperature, concentration and density data – through one, easy-to-use interface. This intuitive design was based upon Emerson’s Human Centered Design discipline. The basic premise is to “Design for Purpose,” with users in mind so that our products meet our customers’ needs. Using this approach, Micro Motion engineered a graphical user interface that allows for intuitive operation, with simplified installation, configuration, maintenance and troubleshooting.

• Some other benefits to the 5700 include:
• Time-stamped history files for process and meter health data – logs for alarms and configuration changes
• Fastest flow response time available
• Suitable with most hazardous area installation practices
• Includes options for analog, pulse, discrete and Modbus outputs and an analog or HART input
• Compatible with Micro Motion ELITE Coriolis sensors (new and previously installed)

Rockwell Automation has introduced a HART-enabled Allen-Bradley FLEX I/O-XT module, an industrially hardened I/O platform that helps OEMs and end users reduce wiring, installation time and enclosure costs.  As industrial applications continue to move into remote locations of the world, the market requires specially designed control equipment to survive extreme environments. The new HART-enabled I/O modules access data from smart field devices that were previously isolated in harsh environments, helping feed performance data into asset management software for a more holistic view of operations and maintenance needs.

“FLEX I/O modules remain one of the top selling distributed I/O platforms today,” said Chan Wai, product manager, Rockwell Automation. “The HART-enabled FLEX I/O-XT module further strengthens our portfolio, and is an ideal fit for the Integrated Architecture and PlantPAx applications from Rockwell Automation with extreme environments.”

The FLEX I/O-XT modules are conformally coated to protect against corrosives, dust, gases, salt, condensation, humidity and fungal growth. This industrial hardening eliminates the need for an enclosure, and the additional installation and energy costs associated with auxiliary heating and cooling systems.

The industrial coating to protect from airborne pollutants and moisture, paired with a minus 20 C to 70 C (minus 4 F to 185 F) temperature range, make the FLEX I/O-XT modules ideal for environmentally demanding environments, including energy and power generation, water/wastewater and on-ship applications.
