TSI Model 4143 Mass Flow Meter (LCD, 0.01-20L/min Air, O2, N2 3/8" conduit) can be used for many gas flow monitoring applications. Whether you are monitoring gas flow in a laboratory or production environment, the TSI General Purpose Mass Flow Meter provides accurate monitoring results that include a variety of data output options. The display version includes a variety of components that make setup and operation quick and easy, and the TSI mass flow meter is specified with a 2% flow reading error. A single TSI mass flow meter has better accuracy over a range than three or more devices with “error as a percentage of full range” ...... have better accuracy compared to three or more.

Fast four-millisecond response ensures measurement accuracy in fluctuating flows. The fast response time of the TSI Mass Flow Meter is particularly well suited for closed-loop control systems and integrated volumetric flow monitoring. The low pressure drop of the TSI mass flow meter minimizes flow loop back pressure and its impact on the system.

The TSI Mass Flow Meter is designed for use in a wide variety of applications.
