AFT Around the World

In early October, I conducted a 5-day training seminar in Lima, Peru. There were seven different companies represented from Peru and Chile. It is always interesting to see the variety of applications for AFT software and Peru was no exception where many of the engineers are involved in mining operations. Peru is a leading producer of copper, gold, silver, phosphate and potash with over $16 billion in exports in 2009. The engineers at the seminar had a variety of active project responsibilities. These ranged from long transport pipelines, to storage and transfer systems, to refining and process facilities. The course emphasized...

Where Did the Name "Fathom" Come From?

A frequently asked question at our training seminars - usually during a break or over lunch - is how we came up with the name "Fathom". More completely, the product is named AFT Fathom ™ and it is considered by many as the world's leading pipe flow modeling software product. The story behind the Fathom name is intimately tied to the story behind the founding of Applied Flow Technology as a company. So let's go back to 1993. AFT Fathom started as a hobby in 1992 while I was working in the power industry as a research engineer. But it was not...

Save Money, Reduce Energy and Improve Sustainability with AFT

The growing emphasis on sustainable business practices and environmental responsibility has impacted AFT software in several areas. In recent years we have added built-in capabilities to AFT Fathom and AFT Arrow to calculate energy usage and to estimate the cost to operate rotating equipment. This is available on the Analysis menu in the “Cost Settings” window. Using AFT Fathom, TME Energy Services Division developed a model of the chilled water system at the University of Arkansas . The project realized an annual energy savings of 1.9 million KWHr and $67,000 in pumping power and $1,200,000 in annual chiller electrical and gas...

Printing Input and Output

You can print all of or select portions of your model data window in order to have a hard copy of your input. Likewise you can print all of or select portions of your output window in order to have a hardcopy of the output. Printing both of these windows allows you to have hardcopies and backups of everything you would need to perform calculation checks on your model. After building your model and entering all of the required data, browse to the Model Data window and click “View/Model Data Control”. After setting up the input data to be displayed, click...

As President of AFT, I often hear from our customers about how one of AFT's software products has helped them solve a problem or made their lives easier. Sometimes I'll notice something in the news and think how AFT's products COULD have helped avoid a problem. Every month, I'd like to share these insights with you in hopes that we can all work together to make our pipelines safer and more efficient. Last week I met an AFT Impulse user at a conference and was reminded of how profoundly our products affect the safety of industrial systems. I made a presentation...
