Sierra's CalTrak® XL is the leading high flow primary gas flow calibrator on the market today. With increased demand for higher flows of process gas, there is a requirement to validate and calibrate high flow gas meters and controllers. Designed to replace aging bell provers, the XL meets that need with an impressive standardized accuracy of +/-0.25% of reading (model XL 500) over a flow range of 5 slpm to 500 slpm or +/- 0.45 % from 5 slpm to 500 slpm (model XL 1500). The flow cell is fitted with low mass borosilicate glass pistons with a low friction coating that oscillate between two detectors to quickly and accurately measure gas flow rates. The design of the allows for increased flexibility and speed of reading. Flow measurements can be taken manually (one reading at a time), or automatically in continuous mode. CalTrak calibrators offer digital communications via RS-232 and USB and come with our CalSoft™ data collection software suite. Make CalTrak a workhorse in your calibration lab and save money by doing your own flow calibration.

PERFORMANCE SPECIFICATIONS Standardized Accuracy* +/- 0.25% of reading 15°C to 30°C (59°F to 86°F), from 5 slpm to 500 slpm +/- 0.45% of reading 15°C to 30°C (59°F to 86°F), from 15 slpm to 1500 slpm CalTrak XL is a true primary standard in every sense of the word, because its accuracy is based upon primary SI units: The interior diameter of the glass measuring cylinder; the length of piston travel within the cylinder; and the time it takes the piston to travel this distance, implying a known volume. Our patented technology, therefore, offers accuracies at the level of national laboratories...
