Product Details

The Mass Flow Meter 40401 features a 22 mm ISO connection. It is calibrated for air only and has a 0-300 L/min range.

Whether measuring gas flows in a laboratory, hospital, clinic, or manufacturing setting, TSI mass flow meters provide accurate results and support multiple data output options. This product comes complete with accessories, making setup and operation fast and convenient.

The TSI mass flow meters are specified as two percent of flow rate reading. One TSI mass flow meter covers the same range as three (or more) percent 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 minimizes flow circuit back pressure and its impact on the system.
