TSI 4000 Analog and Digital Flow Meters

The TSI 4000 Series inline flow meters were designed for ultra-low pressure loss to minimize flow circuit back pressure and its impact on the system. The meters include digital and analog outputs for flow rate, absolute pressure, and temperature. Volume measurements can be made through the RS232 digital interface.

Descriptions of TSI 4000

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

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.
