Description

The Fox Thermal FT4X is a high-precision thermal mass flow meter designed for direct measurement of gas mass flow rates without the need for temperature or pressure compensation. This insertion-style meter features an 18-inch probe suitable for pipes up to 6 inches in diameter, making it ideal for applications in oil and gas, industrial gas monitoring, flare gas measurement, and wastewater treatment. Key features include dual 4-20mA outputs for flow and temperature, HART communication, USB port for configuration, and a built-in gas selection menu with Gas-SelectX technology allowing field selection of up to 10 gases or custom mixes. It offers exceptional accuracy of ±1% of reading + 0.2% full scale for flow, and operates in temperatures from -40°F to 250°F. Advantages over similar products like those from Sierra or Endress+Hauser include its robust explosion-proof housing (Class I Div 1), easy field calibration verification with CAL-V, and lower maintenance due to no moving parts. Drawbacks may include higher initial cost and requirement for straight pipe runs for optimal accuracy. This unit appears new with calibration certificate, suitable for hazardous locations, providing reliable, repeatable measurements in demanding environments.
