Measure Flow, Pressure, and Temperature…all in one instrument! Designed for Performance TSI thermal mass flowmeters incorporate a proprietary platinum film + 4 millisecond flow response sensor design for measuring gas flows in applications demanding fast + High accuracy ±2% of reading response and high accuracy over a wide flow range. TSI flowmeters have + High turndown ratio turn-down ratios greater than 1000:1 due to our thermal flow sensing technology and extensive gas calibration process. The TSI 4000 Series + Convenient analog output of flow rate was designed for ultra-low pressure loss...
