SCADA Solutions Since 1981





SCADA Solutions

For nearly 39 years, DFS has provided hundreds of SCADA (Supervisory Control and Data Acquisition) Systems and thousands of RTUs to our customers throughout the United States. These systems range from small water control utilities and districts to large county-wide wastewater collection systems. Whether big or small, we have your solution.

Browse the list below, or select an image on the left, to see some of what we've accomplished for our customers. Chances are you will find that we've provided a SCADA solution similar to your current needs. Of course if your SCADA application is unique, we can develop a solution that's a perfect fit.

Why Should You Use SCADA?

Traditional automation and control uses hardware interfaces and custom designed algorithms to control a self-contained process. A limited human machine interface (HMI) may be part of these distributed control systems.

SCADA saves you time and money, and removes the potential for human error. SCADA refers to a centralized system that collects, monitors, and stores data from many distributed process control systems. In addition to reducing manpower and travel costs associated with managing remote processes, SCADA systems provide tools for analyzing, reporting, and fine-tuning those processes.

Convenience and Efficiency

In a typical system that doesn't use SCADA, each automated process works in isolation and is disconnected from the other processes in the system. This arrangement makes managing and maintaining the system difficult and time consuming. By adding SCADA, you can gain both efficiency and convenience, because a SCADA system allows you to run many remotely-located processes from one location.

Modern communication products and techniques, such as radio, wireless Ethernet, and cellular networks, bring data from many remote processes and devices to a SCADA server. Users monitor, evaluate, and control all processes from this single point using powerful software tools in the Human Machine Interface (HMI). This is much harder to accomplish in isolated and disconnected automated processes.

Gain Remote Access to Equipment and Processes

Automated processes commonly use gauges, counters, chart recorders, switches, and dials as Man Machine Interfaces (MMI). With a SCADA system, up to the minute status is displayed on workstation computers using animated and static graphics and text. This format allows operators to understand what is going on in the system at a glance. Additionally, process variables can be adjusted right on the screen without the need for an operator to travel to the remote control panel. Screens are available for each process and sub-process from across the system.

Respond to Alarm Conditions Quickly

Without SCADA, remote sites with horns and lights rely on homeowners and passersby to inform operators of alarms. This can be unreliable and can delay response to problems in the system. A SCADA system allows operators to quickly respond to situations - throughout the system - and take corrective actions. Alarms are communicated to the operators in a number of ways: listed and enunciated at workstations, and sent via e-mail and telephone.

Generate Reports Quickly and Easily

Operational reports are often mandated by government regulatory agencies. Reports also help operators optimize process efficiency by showing problems in a process. One limitation of isolated process control applications is the manual effort required to generate reports. Data is often gathered by hand, taking readings from meters and gauges at some time interval. Some process variables are recorded on chart recorders, generating reams of data that must be interpreted. Data is manually input into a computer where calculations are performed creating values for a report. In short, generating reports becomes a time- and labor-intensive task. Because data from multiple remote sites is stored in one location on a SCADA server, reports are created quickly and easily. Operators use reports on a SCADA system to optimize overall system efficiency because all pertinent data is available.

Quickly Analyze System Performance

The use of trends and graphing takes the advantages of reports one step further by displaying the data in a graphical format. Some trending is available in traditional process automation applications: strip recorders generate rolls and rolls of data that must be interpreted manually. Copying and transmitting this data is cumbersome at best. Trends on a SCADA server are much more flexible and useful. Data from analog and digital sources from across the system can be compared on one screen. Process variables are easily understood, so that operators and planners can interpret and analyze process status at any point in time at a glance.

Integrate System-level Automation & Control

Traditional process control is limited to a single process in an isolated location; processes within the system are disconnected. In a SCADA system, integrated system-level process automation is accomplished through the use of ladder logic on the server. System wide control is a powerful feature of a modern SCADA system.

Suppose you choose a SCADA system. What will it take to make it GREAT?

The goal of a good SCADA system is to enhance process automation. Here at Data Flow Systems (DFS) we know how to make it great. From our ability to seamlessly integrate SCADA and process automation to our 24/7/365 customer service department, DFS provides what our customers need. We believe a great SCADA system should present system and process data to your organization in ways that are both meaningful and easy to understand. We also provide great value for your SCADA system purchase. Our SCADA System HMI software is Internet browser based (no special software to install on each workstation) and offers unlimited, license-free seats and free software upgrades for the life of your system.

Yes we can!

At DFS, we not only offer the SCADA products you need, we also offer experienced engineering design, automation and control, and integration services. We will work directly with you to design a solution or with your consultant to develop specification requirements. Our experienced people and respected performance have made DFS a trusted leader in SCADA for nearly 30 years.
