A durable flowmeter for remote applications outdoors A thermal-dispersion, mass-flow sensing technology, the ST50 Flow Meter Series (photo) boasts ±1% accuracy (repeatability ±0.5%) for 2 – 24-in. line sizes and a built-in temperature compensation for reliable measurement over a 40 – 100°F temperature range. There is almost no pressure-drop, according to the firm. The ST50...

    Deregulation of market pricing structures, increased oil-and-gas exploration and drilling costs, fierce competition, and new regulatory requirements have all influenced today’s trend toward quality flow-measurement methodologies. Not only is volume a consideration, but so is the inherent value of the product being measured. From high-value process streams found in the pharmaceutical...

    Flow measurement plays a critical role throughout the chemical process industries (CPI). Repeatable measurements are needed to maintain consistent production and quality standards in a wide range of process-control applications. Inaccurate liquid- and gas-flow measurements can mean the difference between profit and loss, and in some cases, can lead to more serious consequences. This article...

    With typical operations running around the clock, the chemical process industry (CPI) demands high performance from its instrumentation. Today's flowmetering solutions include tools for the entire life cycle of a flowmeter. From engineering, commissioning and start up to operations and maintenance, advanced diagnostics and onsite device-verification features help to maximize plant...

    The usage of Coriolis flowmeters for measuring mass flowrates has become widespread in the chemical process industries, and the range of fluids with which these meters can be employed is likewise diverse. Among those applications, Coriolis flowmeters can readily be applied to cryogenic fluids (contrary to conventional flow-measurement practice with these fluids), provided that the measurement...

    These meters have no moving parts The Vortex PhD (photo) is an inline meter that measures flow of liquids, gas or steam. With a fully welded sensor construction, the Vortex PhD has no moving parts nor holes that can clog, no internal gaskets that can fail and no need for bypass-piping installation. Accuracy is ±0.7% of rate for liquids and ±1.0% for gas and steam with a...

Last month, Emerson Process Management (St. Louis, Mo.; launched the Rosemount 3095 MultiVariable transmitter with FOUNDATION Fieldbus (FF) technology and fully-compensated mass-flow functionality. Said to be a first for the process industries, this extension to the Rosemount 3095 platform adds more intelligent-field-device functionality to...
