Fox Model FT4X Thermal Gas Mass Flow Meter

Product Code: Fox Model FT4X

Manufacturer: Fox Thermal

The Fox Thermal Model FT4X, is the newest Thermal Gas Mass Flow Meter offered from Fox Thermal.

The Model FT4X measures gas flow rate in standard units (MSCFD, SCFM, NM³/hr, LBS/HR, KG/HR & many more) without the need for temperature and pressure compensation.

A free software tool – FT4X View™ – is available for the Model FT4X that allows the user to connect to and configure the FT4X using a PC or laptop.

The CAL-V™ test is used for Calibration Validation on the Model FT4X. This test does the following:

  • Tests the functionality of the sensor and its associated signal processing circuitry
  • Checks for build-up on sensor that could affect calibration
  • Ensures that the meter still retains its original NIST-traceable calibration
  • Checks thermal conductivity (heat transfer) repeatability of the sensor

Use this test according to the manufacturer’s instructions in order to validate the calibration of the meter.
