For remote monitoring and control of your water systems
HyperTAC II Software

We have more than two decades of experience and success providing operationally-oriented radio telemetry SCADA systems using HyperTAC II.

In addition to providing new systems, we also offer a software solution to allow existing Motorola Intrac 2000 users to protect their investment while upgrading economically.

Graphically Driven

 Every system setting and control can be accessed via a graphical user interface. No programming necessary. This easy-to-use software allows multiple users to control and monitor the system at the same time. True multitasking!

Host to Multi-Point and Point-to-Point

SCADA systems can be easily designed to fit your needs. With a host to multi-point system, a central host computer can transmit and receive data with multiple remote sites. Also, with the ability to relay data, each remote terminal unit (RTU) can be used in a point to point system, allowing a large area to be covered with less hardware.

Includes Standard Reports

Detailed station, flow, pump and other reports are all included with our standard system. Viewing of reports, such as pump performance, can allow problems to be diagnosed well before a failure occurs.

Unsurpassed Warranty and Support

We provide a 3-year warranty on our systems. This warranty even includes damage due to lightening!  You can take advantage of our free, 24-hour telephone support and on-site system training. Also, we provide free software upgrades for the life of the system, assuring that you are never left behind.

  • Overview
    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.
  • What will it take to make your SCADA system GREAT?
    The goal of a good SCADA system is to enhance process automation. Here at Northern Data Systems (NDS) 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, NDS 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.
Browse (scroll left or right) the list below 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.
Elevated Storage Tank Automation

SCADA Systems are often used to maintain water storage tank levels with offsite well pump stations. The SCADA system we installed monitors and controls the water level in the elevated storage tank, provides tank level control from several offsite well pump stations, allows operators to specify set-points, displays graphical representations of the tank and the system, provides alarm features, and generates trending and historical data.

The system is programmed to start and stop well pumps based on operator-adjustable tank level set-points. The pressure transmitter continuously measures a tank level variable and transmits a 4-20 mA signal representing the level to the local RTU.

RTUs were installed at each offsite Well location. For each given well pump, there is a start and stop command based on tank level and an alternation scheme. The system monitors the tank level and controls pumps according to the set-points. If the tank level drops, the system activates a pump, monitors the levels, and stops the pump. It also monitors for potential pump failures or failure conditions, and keeps track of the pump usage for allotment purposes. Operator override pump control and pump disable is permitted.


At Northern Data Systems, 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 NDS a trusted leader in SCADA for nearly 30 years.
