Vent Gas Flow Meters for Direct Mass Measurement in Flow Vent (Flash) Gas Applications

Fox Thermal Flow Meters for Vent Gas Applications

Thermal Mass Flow Meters from Fox Thermal are often used to monitor vent gas from tank batteries in the Oil and Gas industry. Vent gas, flash gas, and flare gas can often be tricky gases for some types of technology. Some monitor flow well only at high velocities, and others only at lower velocities. Gas flow meter technology is a popular solution to this problem. The thermal mass flow meter can measure gas flows at very high and very low flow rates.

Advantages of Fox Thermal Flash & Vent Gas Flow Meters

At Fox Thermal, our meters are rugged and have a proven track record of accurate flow rate measurement across a wide range of applications. All Fox Thermal vent gas flow meters are rugged and accurate meters that can be used in a wide variety of applications involving low and high velocity gas flows. With repeatability and a low turndown, Fox Thermal gas mass flow meters were designed to be durable and versatile.

Rising levels of volatile organic compounds (VOCs) in the atmosphere are a subject of general concern and increasing environmental regulation. For instance, US EPA’s 40 CFR Part 98 is comprised of a body of regulations meant to improve air quality. This body of regulations is broken into a multitude of sections dedicated to different industries.

In order to monitor and quantify emissions, VOC concentrations as well as VOC flow rates must be measured to evaluate mass emission rate. Purchasing flash gas flow meters or vent gas flow meters is a common way to measure these emissions.

The major reason for monitoring VOC emissions with a gas meter vent is to provide information for environmental audits. However, VOC monitoring with a flash gas flow meter or vent gas flow meter can also help you:

  • Identify opportunities to reduce emissions
  • Evaluate performance of existing abatement equipment
  • Identify and correct sources of fugitive emissions
  • Demonstrate continual improvement in environmental performance
  • Meet health and safety requirements and improve working conditions
  • Optimize process flows throughout the plant or storage facility

The thermal mass flow meter’s ability to provide a direct reading of mass flow rate without additional pressure and temperature instrumentation makes it ideal for measuring flow rates in flare stacks, ducts and tank vents. A flash gas flow meter or vent gas flow meter from Fox Thermal is the ideal way to measure these emissions. See how the Model FT3 is used frequently for this purpose in this Fox Thermal case study on VOC emissions.
