TSI 40212 (300L/min O2 22mm Tube) embedded mass flow sensor is fast, accurate, and has a very low pressure drop for critical measurement applications. The 4000 series mass flow sensors are specified as 2% of reading. One TSI mass flow sensor covers the same range as three or more "percent of full scale devices" ... with better accuracy at most points.

Fast 4 millisecond response ensures accuracy in fluctuating flows. This fast response is ideal for closed-loop control systems and integrated volume measurements. Low pressure drop minimizes flow circuit back pressure and its impact on the system.
