SIERRA Cal=Trak™ XL Gas Mass Flow Standard

Sierra’s Cal=Trak™ XL is the leading high flow primary standard calibrator in industry and offers a standardized accuracy of +/-0.25%. With increased demand for higher flows of process gas, there is a requirement for a way to validate and calibrate high flow gas meters and controllers.    Like all members of Sierra’s Cal=Trak™ family of products, Cal=Trak™ XL is a primary standard piston prover that operates with the press of a button--assuring you the ultimate in calibration accuracy, convenience, ease-of-use, low-maintenance, and productivity.

Select manual or automatic operation, Push one button, Sierra’s Cal=Trak™ XL measures, displays and outputs the flow of gas, either in mass or volumetric units.  The menu-driven configuration allows you to customize the calibrator for your changing needs.  Cal=Trak™ XL is packaged in a sturdy, field-rugged, molded plastic enclosure making it a worthy day-to-day tool.

The dimensionally-based primary accuracy of all our Cal=Trak™ models is superior to pressure-based secondary methods and is backed by a rigorous uncertainty analysis.  It is used in the manufacture, inspection, validation and recalibration of mass flow controllers, flow meters and many other varieties of flow equipment with flow rates too high for previous generations of primary standards.

The single integrated piston chamber of the Cal=Trak™ XL can measure flows over a 100:1 range, from 5 to 500 slpm!  Used in conjunction with our other Cal=Trak™ models, a metrology lab can be established capable of calibrating gas flow meters over a very broad range of 5 sccm to 500 slpm for a combined turndown ratio of 10,000:1. 

At 33”H x 24.6”W x 12”D, Cal=Trak™ XL fits on any laboratory bench replacing large bell provers with one simple, integrated package.

With hundreds of Cal=Trak™ installations spread across the globe, we have found that with minimal training, Cal=Trak™ can be successfully used by anybody.  The Cal-Trak™ XL is well-suited for applications in many fields where higher flows rates of gas are becoming common:  metrology, semiconductor, analytical, medical, pharmaceutical and quality control among others.  Cal=Trak™ is also CE approved.
