Multivariable transmitters for flow, level measurements

ABB's 266 Multivariable transmitters are designed to directly calculate the mass flow or standard volume flow for gases, vapors and liquids and can correct parameters for discharge coefficient and the thermal expansion of pipelines.

Courtesy: ABBABB's 266 Multivariable transmitters are designed to directly calculate the mass flow or standard volume flow for gases, vapors and liquids with dynamic flow compensation from three process variables: Differential pressure, absolute pressure and temperature.

The transmitters enhance differential pressure flow measurements of DP primary elements such as Orifice Plates, Pitot Tubes, Venturis, and Wedge Meters. Apart from pressure dependent and/or temperature dependent changes to the density of the fluid, the transmitters also correct parameters as the discharge coefficient, thermal expansion of pipelines and primary device, along with the Reynolds number. The 266 Multivariable also offers the advantage that a single device replaces a standard DP transmitter, gauge transmitter, RTD, associated wiring and flow calculator.

In addition, these instruments can measure the level of liquid-filled tanks and boiler drum level with temperature and/or pressure dependent density changes of the process medium. With the inclusion of a tank shape specification, they can also measure liquid volume.

The 266 Multivariable offers the ABB exclusive TTG (Through The Glass) technology. This technology allows configuration of the instrument through the glass of the housing cover via four buttons on the display of the transmitter.

The transmitters contain a standard HART diagnostic called PILD (Plugged Impulse Line Diagnostics) detection. PILD monitors the impulse lines for clogging, identifying a possible fault before the measuring point fails, and signals this fault in a status message both locally and via HART. The 266 Multivariable transmitters also have pulse or frequency outputs for activating external totalizers or for signalling limit-value violation.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
