Mass Flow meter 4040

The Mass Flow Meter 4040 features a 22mm ISO connection. It can be calibrated for air, oxygen, or nitrogen and has a 0-300 liter per minute range.

Whether measuring gas flows in a laboratory, hospital or clinic, or manufacturing setting, TSI general purpose mass flow meters provide accurate results and support multiple data output options. The display versions come 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 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 minimizes flow circuit back pressure and its impact on the system.
