Product catalog summary
Overview
TSI® thermal mass flowmeters are designed for measuring gas flows with high accuracy and fast response times. They are suitable for applications requiring a wide flow range and minimal pressure loss.

Key Features
  • 4 millisecond flow response time
  • High accuracy of ±2% of reading
  • High turndown ratio
  • Low pressure drop
  • Analog and digital outputs for flow rate, volume, pressure, and temperature
  • Built-in temperature and pressure compensation
  • NIST-traceable calibration certificate included

Specifications
  • Flow measurement range varies by model, with low flow models (4140 Series) ranging from 0.01-20 Std L/min and high flow models (4040 Series) up to 300 Std L/min.
  • Accuracy varies by gas type, with ±2% for air or O2 and ±3% for N2 and other mixtures.
  • Pressure measurement range is 50-199 kPa absolute with an accuracy of ±1 kPa.
  • Temperature measurement range is 0-50°C with an accuracy of ±1°C at flows greater than 1 Std L/min.
  • Response times for pressure and temperature measurements are less than 4 ms and 75 ms, respectively.

Model Variations
  • Low Flow – 4140 Series: Designed for smaller flow rates with a compact size.
  • High Flow – 4040 Series: Suitable for larger flow rates with a larger size.

Accessories
  • Power supplies for different regions
  • Computer and analog cables
  • RS232 Serial Command Set Manual
  • Operator’s Manual
  • Calibration Certificate
  • Optional battery pack/stand and carrying case

Mass Flow Meters for Gases-2

Measure Flow, Pressure, and Temperature… all in one instrument! Designed for Performance 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. RS232 Interface For...
