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.

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.

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.

Ultra-Low Pressure Drop

TSI flow meters are designed for ultra-low pressure loss to minimize flow circuit back pressure and its impact on the system.

High Accuracy

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.

Fast Response Time

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.
