TSI 4140 and 4040

Hover to zoom

TSI thermal mass flowmeters include a proprietary platinum film sensor design for measuring gas flows in applications demanding fast response and high accuracy over a wide flow range. These models have various features for example a 4 millisecond flow response, high accuracy ± 2 % of reading and low pressure drop including many others. The TSI 4000 / 4100 series was designed specifically for ultra-low pressure loss to minimize any desireable effects the flowmeter can have on the readings under testings.
