Sierra - Model CalTrak 800 -Highest Accuracy Gas Flow Calibration Equipment

All of our CalTrak models contain a nearly frictionless graphite piston that moves freely inside a borosilicate glass tube. When the parallel bypass valve is closed, the gas flow is directed into the tube to push the piston up. Two photo-optic sensors detect the piston as it travels past.

The distance the piston travels between the two sensors is precisely defined and represents a known volume. Accurate crystal-based timers drive a microprocessor which calculates the rate of rise. This defines the volumetric flow rate.  At the same time, extremely accurate temperature and absolute pressure sensors collect data used to calculate the mass flow rate.
