HISTORY
After more than 20 years of manufacturing thermal gas mass flowmeters, Fox Thermal Instruments continues to lead the market in innovative, reliable, accurate, and full- featured flow meters.
Fox Thermal Gas Mass Flow Meters from Fox utilize the thermal sensing principle, a proven, accurate direct mass flow measurement technology. This technology performs at high levels of accuracy for a wide variety of gases

MASS FLOW METER
- Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
- Fox Models FT2A and FT3 are equipped with the PowerPro™ Sensor while the Model FT1 has the DDC Sensor™.
- Both thermal mass flow sensors consist of two Resistance Temperature Detectors (RTD’s).
- The sensor elements are constructed of a reference grade platinum wire wound around ceramic mandrels that are inserted into stainless steel tubes.
