Thermal mass flow meters designed for gas flow measurement

Whether measuring gas flows in a laboratory or manufacturing setting, TSI thermal mass flow meters provide accurate results with multiple data output options.

The TSI 4000 Series inline flow meters were designed for ultra-low pressure loss to minimize flow circuit back pressure and its impact on the system. The meters include digital and analog outputs for flow rate, absolute pressure, and temperature. Volume measurements can be made through the RS232 digital interface.
