The CalTrak® XL is the leading high-flow primary standard calibrator on the market today. The XL is used for calibration and verification of mass flow meters, controllers, variable area flow meters, and precision in-situ calibration of industrial flow meters and controllers.

With increased demand for higher flows of process gas, there is a heavy demand to validate and calibrate high flow gas meters and controllers. The cost to use third-party calibration houses to calibrate and certify higher flow devices is three to four times the cost of an ordinary low flow device up to 50 slpm.
