Fractional Flow Control Valves from Swanson Flo

For Critical Fractional Flow Control of Liquid, Gas, or Steam

LowFlow control valves have applications in OEM, laboratory, and pilot plant applications. Installations such as these frequently require valve trim changes to meet varying flow requirements for a given application. Monel,  Hastelloy, Alloy 20, Titanium, Kynar, and Inconel are just a few of the materials LowFlow offers to address your material compatibility challenges.

LowFlow control valves require no special tools for trim changes. Their bolted body design means you don’t even have to take the valve out of line for trim changes or maintenance.

LowFlow Valve provides products across an incredibly diverse range of industries and applications, from operating in cryogenic applications down to -425°F (-254°C)  to temperatures above 1000°F (538°C).

The Mark 708 valve provides accurate control on fractional flow applications. It is a complete line of pneumatic and electrically actuated control valves designed to enhance performance to ensure precision control on your most critical microflow applications.

Gas Flow Measurement & Control - Aeration Applications

Many processes include gas flow measurement and control. Gas flow meters are standard in laboratories, machinery, industry, hazardous areas, and various markets, including the analytical market, the chemical industry, renewable energy, the semiconductor industry, the food and beverage industry, and surface treatment. 

Applications for Aeration 

Aeration is when air, oxygen, carbon dioxide, or other gases circulate, mix, or dissolve in a liquid or substance. 

Aeration applications are typical in food and beverage markets, wastewater treatment, fish tanks, and fish farms. Controlling oxygen levels in beer brewing and winemaking, for example, allows fermentation. Milk, sparkling water, and other carbonated beverages, such as cola require a throughflow of gases to remove odors or add CO2. Industrial gas flow control, similar to air pumps in a fish aquarium, is used to aerate ponds to grow fish or algae. 

Gas Flow Aeration Markets:

• Winemaking and beer brewing 
• Production of carbonated beverages 
• Fermenters and bioreactors 
• Treatment of wastewater 
• Farms for fish and algae

Turbine Flow Meters

Turbine flow meters (Badger Meter / Blancett)

Turbine flow meters are process instruments used in a variety of industrial applications to measure the flow of a fluids. These types of flowmeters operate under the simple principle that the rotation of the turbine will be constant as the turbine is acted upon by a fluid passing through the flowmeter.

Turbine flow meters use the mechanical energy of the fluid to rotate a turbine blade in the flow stream and provide precise and accurate flow measurement. The flow impinging upon the turbine blades causes the rotor to spin. The angular velocity of a turbine flow meter is proportional to flow rate. The rotational velocity of the turbine is interpreted as an electrical frequency output through the use of magnetic pick-ups. As each turbine blade passes by the magnetic pick-up coil, a voltage pulse is generated which is a measure of the flow rate. The total number of pulses gives a measure of the total flow which can be totalized with a maximum error of a single pulse.

The relationship of the angle of the turbine meter blades to the flow stream governs the angular velocity and the output frequency of the meter. The sharper the angle of the turbine blade, the higher the frequency output.

Easy to maintain while also boasting reliability, turbine flow meters are known to be cost-effective solutions that make an ideal device for measuring flow rate. Aside from excellent rangeability, they also provide high response rate and high accuracy compared to other available types of flow meters. Turbine flow meters are sturdy, need very little maintenance, and seldom exhibit much deviation in performance.

Turbine flow meters (Hoffer Flow Controls)

These meters are used in multiple industries to reliably measure the velocity of a variety of liquids, gases and vapors over a very broad range of flow rates, temperatures, and viscosities. Turbine flow meters are used to provide measurement information in cryogenic applications, crude oil production, chemical processing, blending systems, storage, off-loading, product loading, and many other applications across many industries.

Advantages:

• Accuracy
• Excellent repeatability and range
• External power not required
• Good fro cryogenic applications
• Good for extreme pressures and temperatures
• Easy to install

Disadvantages

• Material availability
• Not recommended for contaminated media or slurries
• Error due to wear

“Why do we need to measure in mass flow? What is the difference between ACFM and SCFM? Why are pressure and temperature correction not required when measuring with a thermal mass flow meter? What is the thermal mass flow measurement theory? What are common applications to use thermal mass flow meters?” The white paper below attempts to explain these questions and more.
