TSI thermal mass flowmeters incorporate a proprietary platinum film sensor
design for measuring gas flows in applications demanding fast response
and high accuracy over a wide flow range. TSI flowmeters 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 any undesirable effects the flowmeter
can have on the readings when installed in-circuit.
