The TSI 4140 Series Mass Flowmeters can be used for a multitude of gas flow measurement applications. Whether measuring gas flows in a laboratory or manufacturing setting, general purpose flowmeters provide accurate results with multiple data output options. The display versions come complete with accessories making setup and operation fast and convenient.

The flowmeters are specified as two percent of flow rate reading. One flowmeter covers the same range as three percent (or more) of full scale devices, with better accuracy at most points. Fast four millisecond response ensures accuracy in fluctuating flows. This fast response time is ideal for closed-loop control systems and integrated volume measurements. Low pressure drop minimises flow circuit back pressure and its impact on the system.
