The 491M/B/SD Gas Standards Generator dynamically blends precisely known gas standards with parts-per-trillion (ppt) analyte concentrations. The system uses two stages of dilution to achieve ppt concentrations. The first combines emission of analyte vapor from a Trace Source™ permeation tube with a precisely known flow of pure dilution gas to form a parts-per-billion concentration primary mixture. In the second, an aliquot of this mixture is further diluted to form the ppt mixture. KIN-TEK Laboratories Inc., La Marque, TX, 409-938-3627,

While traditional orifice-based DP flowmeters have only been able to maintain accuracy over a narrow 3:1 operating window, Emerson’s Rosemount® 3051S Ultra for Flow can support up to 14:1 flow turndown with better than a 0.5% of reading accuracy. Performance with the meter specified as a percent of reading, instead of the traditional percent of span. This method of specification eliminates the performance degradation inherent in the nonlinear relationship between flow and differential pressure.
