TSI 4140 low flow gas monitor with power supply, cables, inlet filter, user manual and calibration certificate

Overview

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.

Features

  • 4 millisecond flow response
  • High accuracy ± 2 % of reading
  • High turndown ratio
  • Low pressure drop
  • Convenient analog output of flow rate
  • Versatile digital output of flow rate, volume, pressure, temperature
  • Built-in temperature and pressure compensation
  • NIST-traceable calibration certificate included at no additional cost
  • RS232 Interface for digital outputs and configurable device options
  • Set analog output zero and scaling
  • Specify start/stop trigger levels for volume measurement
  • Set update rate for LCD display
  • Set sampling rate for analog and digital outputs
  • Select gas calibration
  • Select either standard or volumetric flow measurement
  • Set display units for model 4140 to L/min or cm3/min
  • Compute volume
