Why Choose DFS?
Data Flow Systems, Inc. (DFS) was established in 1981 to manufacture SCADA solutions specifically for water and wastewater utilities in Florida. DFS has gained national recognition for its durable and obsolescence-proof TAC II SCADA System, as well as its technical capabilities and guaranteed radio links. Today, DFS is recognized as an industry leader, providing remote monitoring and control for remote facilities, and water & wastewater treatment plant automation systems. Our latest product, "Symphony Harmonious Pump & Flow Management" has been proven to significantly reduce lift station pump run times and pumping energy costs.
The Company's corporate headquarters is located in Melbourne, Florida and consists of a 30,843 square foot facility encompassing sales, engineering, radio study and licensing, customer service, product manufacturing, certified UL-508 panel shop, and warehousing. We currently employ over 50 full-time employees all dedicated to water and wastewater SCADA systems and applications.
With our combination of design, installation, and service capabilities, DFS offers complete SCADA solutions. Emphasis is placed on developing long-term relationships as the supplier of choice for SCADA applications. At the present time there are over 250 individual TAC II SCADA Systems with more than 10,000 RTUs installed and operational throughout the United States. DFS’ TAC II SCADA System installation base ranges from small Water Control Districts to large WW Collection Systems, and Automated Plant Control Systems. Our single largest user, Collier County Florida, currently has over 700 DFS RTUs for the monitor and control of their sewer lift stations.
The sections below further explain why you should choose DFS for your next SCADA project.
A True Obsolescence-Proof System
The average life of a SCADA system in the water and wastewater utilities market is around seven to ten years. While poor design and selection of materials accounts for the premature demise of many systems, it is more often technical obsolescence of the system that brings about its end.
Although the DFS TAC II SCADA System is designed to withstand the effects of Florida's harsh environmental conditions, careful planning in the engineering and design phase produced a system that has also achieved "technical durability." The TAC II SCADA System is a continuously evolving system for nearly 36 years, and all new products maintain a downward compatibility with all older versions - allowing a utility to maximize their investment over the long term.
Over the years utilities have purchased new and improved DFS products to expand the "original installation." All DFS products incorporate current state-of-the-art technology, but maintain downward compatibility with older versions, demonstrating an obsolesce-proof design that can be found in no other SCADA system.
All DFS I/O modules, Pump Controllers, Powers Supply Modules and Radio Interface Modules are completely backward compatible with older versions and revisions of like type. New products are designed with pin-for-pin compatibly of like type and require no rewiring, adjustments, straps or configuration adjustments (plug and play).
In addition, DFS provides support and repair for every TAC II SCADA product that we have ever manufactured. DFS does not have "generation systems" with a limited life cycle of availability and support. No matter how old, if we built it we will service it. DFS doesn't require annual maintenance contacts or renewal support program fees.
Industry Leading Customer Service
DFS has relied heavily on service and support to succeed in the SCADA business. This is the key ingredient to establishing and maintaining a long term relationship with our customers. The following valuable services are available from DFS, most of which are provided free of charge.
DFS' TAC II SCADA system was designed so that its operation is easily operated by utility personnel. This fact, coupled with the fast and efficient support offered by DFS, means that a utility does not need to bolster its infrastructure with additional I & C personnel in order to operate and maintain the SCADA system.
"Symphony - Harmonious pump & flow management" is a patented technology that is available only from Data Flow Systems, Inc. (DFS). Symphony utilizes SCADA to coordinate the system-wide operation of sewer lift stations for the purpose of reducing force main pressures and equalizing flow into a master lift station and/or wastewater treatment plant. The result is a significant reduction in energy costs and a solution to daily peak-flow problems.
Symphony requires the use of a DFS Hyper SCADA Server (base station) and the TAC Pack TCU (pump-controller RTU) at each lift station. A combination of functions provided by both the Hyper SCADA Server and TAC Pack TCU are utilized by Symphony.
In this facet, Symphony is essentially a coordinator that addresses the random asynchronous operation of each lift station operating on a common force main. Symphony synchronizes the pumping activity on a minute-by-minute basis. Head pressures are reduced and pumps begin to operate more effectively and efficiently. The results are diminished pump-run-times, less maintenance costs, and a reduction in pump energy expenses!
Peak-flow problems occur in a collection system several times a day. There are opportunities to reduce peak flow in virtually every collection system. Symphony employs a technique that levels the flow by systematically managing the peaks and valleys over a 24 hour period. Overflows at the head-works can be prevented, the need for equalization basins may be eliminated and the biological treatment systems work more efficiently.
Radio Communications Experts
DFS personnel are extremely meticulous when it comes to radio communications. No amount of attention to HMI software or RTU hardware can overcome a poor radio communications link. This most critical area is commonly overlooked by many suppliers and integrators. DFS brings an abundance of RF experience and communications tools to a SCADA project. Consider that:
Open Architecture System
Special Projects Department
All of our special projects are assigned to our Systems Engineering Department. We define “special projects” as Remote Terminal Unit (RTU) applications that require customized panels and/or programmable logic controllers (PLCs) for use in our SCADA Systems. These applications range from complex pump stations to complete plant control systems. DFS is a certified UL-508 panel shop. We design and build both off-the-shelf and custom RTU panels to the highest standards of customer expectations. RTUs can be labeled and certified UL 508A. All wiring is in accordance with the latest N.E.C. codes and J.I.C (Joint International Committee) conventional standards.
Our Systems Engineering Department provides complete engineering of your panel package, specifying the size, material, mounting, layout and wiring. All panels are manufactured using the highest quality components from our suppliers or customer specified suppliers. Every panel built must pass a rigid performance acceptance test before leaving the factory. Every input and output is thoroughly checked and documented.
Our approach ensures proper operation upon delivery. We provide PLC programming, customized graphical HMI screens, installation, commissioning and startup services, including training of operator personnel and technicians. Operations and Maintenance Manuals are provided for each panel and include a descriptive control strategy, hardware and software configurations, final electrical and mechanical drawings, HMI screen illustrations, PLC program, bill of materials and component specifications.
Surge Protection Features
DFS equipment incorporates exceptional surge protection features as a standard practice. DFS Remote Terminal Units (RTUs) are designed for the high incidence of lightning in Florida and include a THREE YEAR LIGHTNING WARRANTY.
The following are standard with DFS Systems and RTU products:
