TSI 40242 (300L/min O2 3/4" 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.
