Product Details

Whether measuring gas flows in a laboratory or manufacturing setting, TSI mass flow meters provide accurate results with multiple data output options. The display versions come complete with accessories making setup and operation fast and convenient.

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