THERMAL MASS 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.

Our flow meters have turn-down ratios greater than 1000:1, due to our thermal flow sensing technology and extensive gas calibration process. The TSI 4000 Series was designed for ultra-low pressure loss to minimize minimize flow circuit back pressure and its impact on the system.

TSI air 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.
