Toro announced the latest upgrade to its popular AquaFlow drip irrigation design software, AquaFlow 4.0. To improve user access and convenience, AquaFlow 4.0 can now be used online. The new program format includes expandable panels that automatically adjust to multiple screen and font sizes, and allow instant visibility of design decision results by scrolling. "Our customers asked for Web-based functionality, and we responded," says Inge Bisconer, technical marketing and sales manager for Toro Micro-Irrigation. "In addition, we added many other requested features that make the program more informative and powerful than ever before."

For example, pull-down menus allow users to easily create new Customers and Projects, and easily select program features, such as Mainline Design, Custom Laterals and Pipes, Options, Common Formulas and Help. In addition, lateral quantity per block, number of laterals per block, submain and mainline irrigation travel time, and submain velocity vs. distance are now reported as well. "AquaFlow is used in over 120 countries worldwide, so the new feature of allowing custom submain and mainline pipe sizes will be very popular in regions with nonstandard equipment," continues Bisconer.

AquaFlow supports Toro's Aqua-Traxx and Aqua-Traxx PC premium drip tape, Neptune flat emitter dripline, as well as BlueLine Classic and BlueLine PC premium dripline laterals. In addition, multiple pipeline choices include Toro Oval Hose, Toro Layflat and PVC pipe. As in previous versions, multiple slopes can still be entered for laterals, submains and mainlines; and submains and mainlines may be telescoped with multiple pipe sizes.

An important feature of AquaFlow is easy comparison between two lateral choices via both data and a visually friendly, color-coded Uniformity Map. "Sometimes a picture is worth a thousand words, or numbers," Bisconer says. "Design strengths and weaknesses are instantly revealed in AquaFlow's Uniformity Map."

AquaFlow designs can be saved, exported and imported. Or, users can print or save to a pdf. In addition, users can select from the English or Spanish language, and standard or metric units. Offline usage will still be supported if the program is downloaded, and a comprehensive User Manual is available in both English and Spanish. "We know that making the right choices in drip irrigation design can be challenging," concludes Bisconer. "We believe that AquaFlow will help designers make better decisions to optimize the investment in drip irrigation."
