4000 Series Analog and Digital Flow Meters
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.
TSI flow meters incorporate a proprietary platinum film sensor designed for measuring gas flows. This enables their use in applications that demand fast response and high accuracy over a wide flow range.

Our flow meters have turn-down ratios greater than 1000:1 due to our thermal flow sensing technology and extensive gas calibration process.
TSI flow meters are designed for ultra-low pressure loss to minimize flow circuit back pressure and its impact on the system.
TSI gas mass flow sensors are specified as 2% of reading. One TSI mass flow sensor covers the same range as 3 (or more) full scale devices, with better accuracy at most points.
The four millisecond response time of the TSI mass air and gas mass sensor is ideal for closed-loop control systems and integrated volume measurements, and it ensures accuracy in fluctuation flows.
