Thermal Mass Flow Meters for Industrial Applications

Industrial Gas Flow Meters must be rugged, packed with features and options, and ready to measure out of the box.

Here are some great features of the award-winning industrial gas mass flow meters by Fox:

  • Easy installation with insertion and inline style flow meters
  • A no-moving-parts design

carbon during cast iron and steel production. Blast furnaces are often fed an oxygen injection that must be monitored by a flow meter that can operate in steel manufacturing plants.

Nitrogen is used more often as a shielding gas to protect processes against ambient air and its oxidizing components (moisture, oxygen, carbon dioxide). Nitrogen may also be used in a purification process in aluminum production.

High quality welding and metal production require the absence of ambient air and its main components. Argon or argon-gas mixes are used as shielding gases or to degas liquid steel for higher quality products.

gases, such as hydrogen or nitrogen, or multiple component gases, such as hydrogen sulfide. Chemical process and petrochemical gases include the uses of halogens for oxidation. Halogens include iodine, chlorine, fluorine, and bromine. These chemical processing gases are used in chemical reactions to produce halide ions, or salts. Halogens are elements that will react with most metals, making them useful in many chemical processes. Other common chemical process and petrochemical gases include oxygen for creating building block chemicals such as nitric acid and ethylene oxide; nitrogen for providing an inert, nonflammable processing environment; and hydrogen for manufacturing ammonia and methanol, as well as for hydrogenation processes to produce soaps, plastics, insulation, and other specialty chemicals.

levels. Refineries require large quantities of gases to control various processes. Pure oxygen, for example, is used to increase the efficiency of wastewater treatment. Adding oxygen to the air in a Claus plant can help increase plant capacity and remove bottlenecks, also improving ammonia conversion by removing sulphur oxides (SOx). Oxygen enrichment in a fluid catalytic converter can also increase capacity and give operators the flexibility to handle heavier feeds and loads by removing nitrogen oxides (NOx).

Hydrogen plays an essential role in producing cleaner burning transportation fuels. It is essential in today’s refining industry for upgrading heavy crude oils into refined fuels, and helping to meet increasingly tighter transportation fuel specifications.

Nitrogen is used to blanket storage tanks and purge pipelines, nitrogen can also strip Volatile Organic Compounds (VOCs) from wastewater and reduce VOC emissions.

manufacturing process. The facilities have vast compressed air systems that are not immune to costly leaks or inefficiencies. Natural gas is also used for various types of production equipment. Ventilation air flow on the production floor, the HVAC system, and the paint booth are all places where gas flow measurement can help check for inefficiencies.

Testing radiator heat exchangers and torque converters for leaks is a common use for helium. Helium can also be mixed with argon to improve shielding gas characteristics for laser welding or used in the production of air bags. It is also important for high pressure gas quenching commonly used with low pressure carburizing to minimize distortion in critical components.

Oxygen is used in foundries that make automotive coatings, as a plasma cutting gas, an assist gas for laser cutting, and is sometimes added in small quantities to shielding gases.

As a component of heat treating atmosphere, hydrogen reacts with oxygen to produce a bright finish on steel parts. It is also used, either alone or as part of a mix, as a quench gas for high pressure gas quenching because of its high heat transfer properties. When used as an alternate fuel, in either a fuel cell or directly in an internal combustion engine, hydrogen also plays a key role in reducing emissions.

Assembly plants, use argon in combination with other welding gases to weld auto components such as exhaust systems, suspensions, seats, axles, and other components in order to block ambient air that might reduce the quality of welds with any material. It’s also commonly used in airbags.

Nitrogen is ideal for processes like tire curing, autoclave inerting, and heat treating for various automotive components. It is also used as an assist gas for laser cutting and enhances plasma-cutting processes. It can also be used to shrink-fit engine and transmission parts, and to manufacture electronic components for seats, stereo systems, anti-lock brakes and air conditioning.

industry. Temperature control engineering can help meet these goals, with the right gas efficiencies tied into the procedures. Carbon Dioxide, Nitrogen, Oxygen and Ethanol are the most common gases used in these processes.

As a gas, Carbon Dioxide is used in bench top incubators. In manufacturing, it is used in super critical fluid chromatography.

Nitrogen is commonly used for blanketing — protecting a process from moisture intrusion, oxidation, degradation and contamination. Additional uses include purging, pressure transferring, mixing and capturing air emissions.

Ethanol is used for pill coating. Uncoated tablets (or pills) are fed into a tumbler where a small-bore feeder sprays a bonding mist of the ethanol carrier, a color tint, a lubricant, or even the drug itself. Depending on the type of coating, the tablets are tumbled anywhere from 30 minutes to 4 hours, with close monitoring of the ethanol feed, temperature, and humidity.

The ethanol concentration in the exhaust is directly proportional to the coating thickness on the tablets. A too-high ethanol level means a too-thick coating, so the spray mist ratio is decreased. The ethanol proportion in the exhaust then verifies the feeder setting.

the chemical industry. While Nitrogen can be used in pressurization, it can also be used as a propellant or as a shield gas for materials that react to oxygen. The production of ammonia along with a host of non-edible oils, plastics, and insulation require the use of hydrogen gas. Pure oxygen is used to produce a number of important chemicals or increase production capacity and efficiency of oxidation processes.

For fish farms, dissolved oxygen is a critical part of raising healthy fish. It is also needed in wastewater treatment using aeration and aerobic digestion processes.

The beverage industry is dependent on carbon dioxide as the essential ingredient in carbonated beverages. It also helps with cooling, chilling, and freezing applications.

Besides Carbon Dioxide, Nitrogen is also widely used as a cooling or freezing agent for quick frozen foods. It also helps guard against spoilage, discoloration, and food packaging.
