AFT and INTELLIQUIP CREATE TWO-WAY LINK for INTERNET PUMP SELECTION
AFT Fathom and AFT Mercury are now able to directly transfer pump operating point information to Intelliquip’s web-based pump selector, Intelliquip Selector™, via the Internet. Candidate pumps selected in the Intelliquip Selector can then be transferred back to AFT Fathom or AFT Mercury where the pump data can be immediately applied to pump junctions in the model and saved to an AFT Fathom / AFT Mercury database.
Intelliquip's Selector is a powerful tool for selecting pumps and this link is a natural match for AFT Fathom's and AFT Mercury's capabilities in determining pump operating requirements and modeling how a specific pump will interact with the system.
This new capability is included in the latest releases of AFT Fathom and AFT Mercury, as well as in the demos for both, and all are available for download at http://www.aft.com/customer/download.php.
An online tutorial is available explaining how to access the new feature and may be viewed clicking here ftp://209.126.140.18/viewlets/IQ_link_viewlet_swf.html
Currently the login for online selectors for Paco Pumps and Johnston Pump are 'hard wired' into AFT Fathom and AFT Mercury. As additional pump manufacturers start using the Intelliquip Selector, you can easily record their login information in AFT Fathom and AFT Mercury so they are immediately accessible .AFT TO EXHIBIT AT SAVING WATER 2003 CONFERENCE
AFT will be exhibiting at the Saving Water 2003 conference August 14, 2003 in the Sheraton Denver West in Lakewood, CO.
Hosted by the U.S. Department of Energy and the Colorado Governor’s Office of Energy Management and Conservation Saving Water 2003 will cover innovative solutions to address short and long term water and energy management issues, including.
- Optimizing Water and Energy Using Systems
- Securing Program Assistance / Financing Alternatives P>
- Using Innovative Technologies to Save Water.
Speakers include local and national experts who will provide information and analytical tools to improve water operations.
AFT will be highlighting AFT Mercury and its ability to yield significant cost savings and energy usage reduction using life cycle cost optimization.

Tips
MERGING TWO MODELS TOGETHER
Models may be merged together by selecting Merge... from the File menu. Before starting this process, it is always advisable to save your current model. You will be asked for the file name to merge into the current Workspace. The model being merged in will be placed on the Workspace and each object will be selected. Move the merged model by positioning the mouse pointer on a selected junction, holding down the left mouse button and dragging it to the desired location on the Workspace. If you accidentally click somewhere off the selected items they will be come unselected and it may be more difficult to move the merged model into position. If this happens, simply reload the original model and start the merging process over again.
BUILDING LARGE MODELS - THE BUILDING BLOCK APPROACH
Very large and complex models may be constructed by building smaller models and merging them together (see tip above). This can have a couple of advantages, including:
- Running the 'building blocks' allows you to more easily identify and resolve any problems that may exist with the model more easily than when dealing with a large model
- It can be easier to understand how parts of a large system react to varying conditions by looking at them separately
- Sometimes it's simply easier to keep track of the model as you build it in smaller, 'bite size' pieces.
Of course you don't have to run building blocks, they can be non-running sub-assemblies that are merged into the larger model. If you do want to run the building block, you'll need to create appropriate boundaries. For example, if your building block is going to connect to a header, you might want to include an assigned pressure junction in the building block at the header connection point with a pressure setting approximating the anticipated supply pressure from the header. If the building block is that portion of a system downstream of a pump, you might use an assigned flow junction set at the expected pump flow.
Of course when you merge the building blocks into the large model, don't forget to delete these temporary boundary junctions.
