Emerson expands range of two-wire transmitters
Loop-powered model 2200S transmitter now available on wider range of Coriolis meter line sizes. See photo. Link to video.
After introducing its first two-wire Micro Motion Coriolis meters last year, Emerson Process Management is expanding the range of line sizes available with this new technology.
The company says the new transmitter is designed for applications that require the precision and multi-variable capabilities of a Coriolis design, but where only loop power is available. Micro Motion devices have traditionally required external power, which limited their deployment in areas where this is not available.
Micro Motion two-wire Coriolis meters deliver +0.10% liquid flow, +0.0005 g/cm3 liquid density accuracy, and +0.35% gas flow accuracy in process control applications. With no moving parts, these meters require no maintenance and are available in a variety of materials of construction. With the new line extension, two-wire Micro Motion meters can handle flow rates from 0.0075 lb/min (2 kg/h) up to 20,000 lb/min (545,500 kg/h).
The intrinsically safe Model 2200S transmitter is suitable for a range of process conditions and has C1D1/C1D2 and Zone1/Zone 2 hazardous area approvals. Equipped with MVD digital processing technology, the transmitter delivers multivariable and diagnostic information via HART communications.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
