Not only will you experience great customer service from Fox Thermal and its representatives, but you will also avoid the long lead times of other brands.
Pure and mixed gases are used in manufacturing processes for pharmaceuticals, vehicles, electronics, and many more applications. These gases must maintain high purity or else they risk diminishing product quality.
Large shops or manufacturers often store gases on-site and then pipe the gas to equipment. Measuring the flow of gases to track usage and compare to purchase manifests allows operators to find inefficiencies or leaks.
Detecting leaks early is crucial to maintain stock and keep costs under control. Finding inefficiencies early can allow the operator to make key decisions for maintenance or replacement strategies.
Fox Thermal mass flow meters provide the ideal solution to control leaks with easy installation, a no-moving-parts design, and a wide turndown (up to 1,000:1, 100:1 typical).
Pure gases are used in a multitude of ways across different industries, requiring accurate flow measurements. Pure gas flow monitoring is essential for specialty gas producers of nitrogen, argon, carbon dioxide, hydrogen, oxygen, etc.
Other applications for pure gas flow meters include food processing and beverage manufacturing, fluid bed dryers, water purification, tablet and pill coating, welding, annealing, and purge monitoring.
Fox Thermal manufactures the following thermal mass flow meters for pure gas flow measurement:
When measuring pure gas flow, the flow meter must be calibrated to the actual gas composition. Fox Thermal’s Gas-SelectX® gas selection feature - available on our FT1, FT4A, and FT4X flow meters - allows the user to easily switch from monitoring the flow of one gas to another.
So, for example, Gas-SelectX® comes with a Pure Gas menu, allowing the user to change from measuring pure Nitrogen to pure Oxygen. This avoids sending the meter back to the factory for recalibration to the new pure gas type - eliminating the time out of service, process downtime, and service charges from manufacturers.
Another key feature from Fox Thermal, the CAL-V™ Calibration Validation test feature, is available on the FT1, FT3, FT4A, and FT4X flow meter models. A CAL-V™ test can be run anytime and under process flow conditions.
The test produces a pass/fail result that ensures the flow meter retains its NIST-traceable calibration from the factory. This allows the user to avoid shutting down the process while checking that the meter is still measuring the gas flow accurately.
By offering these features, Fox Thermal helps make downtime a thing of the past.
If you’re not sure which flow meter is right for your needs, our Help Me Choose app walks you through a short series of questions to help you choose the ideal meter.
Simply enter your process data and measurement requirements into our automated product configurator. Drop-down menus and Help icons will guide you to answer each question.

The FT1 is the most popular flow meter for pure gas applications. Features include a list of pure gases in the Pure Gas menu on Gas-SelectX®, Calibration Validation with CAL-V™, a great price point, and a short lead time.
The Model FT2A has a large selection of communication protocol options available. Options include BACnet MS/TP, RS485 Modbus RTU, Profibus-DP, DeviceNet, or Ethernet Modbus TCP. Ideal for measuring Argon shielding gas or other atmospheric gas needs.
Fox Thermal’s Model FT3 can be used to measure Hydrogen in its purest form or mixed with other gases. These thermal mass flow meters come with FM/FMc, ATEX, or IECEx approvals and NIST traceable calibration for higher accuracy.
The Fox Thermal Model FT4A includes the Gas-SelectX® expanded gas selection menu, including the Pure Gas menu, and the CAL-V™ calibration validation feature. It is CE, FM, and FMc approved, along with ATEX and IECEx. Applications include gas separators and vapor recovery units.
The Fox Thermal Model FT4X thermal mass flow meter comes with a BLM accuracy-compliant data logger which maintains a 7-year history. Includes the Gas-SelectX® & CAL-V™ calibration validation features. The FT4X flow meter is available cleaned and bagged for Oxygen service.
One answer to cleaner global energy supplies is the conversion of fossil fuels to hydrogen. Accurate pure gas flow measurement solutions, like thermal mass flow meters, are key to efficient process control for hydrogen applications.
There are a few key characteristics to consider when choosing the best flow meters for pure gas testing applications.
Plant managers and maintenance managers often use several thermal mass flow meters to determine precisely where their valuable high-purity gases are being consumed and possibly wasted.
