The Challenge:

WBUD operates 32 pump and tank stations spanning multiple counties. All sites required automation, with access to comprehensive device management—both locally and remotely—across an expansive area.

Our Solution:

Each site received a programmable logic controller (PLC) and human-machine interface (HMI) for automation and control. A radio network connects all sites to a central supervisory control and data acquisition (SCADA) system, providing long-distance operation and data monitoring.

The Result:

CIMON’s UltimateAccess SCADA program allows real-time and historical data from all sites to be accessed from any location. Schedules and programs can be updated remotely, removing the need for time-consuming and expensive on-site visits.

Project Summary:

With funding from the Tennessee Valley Authority, Watt Bar Utility District (WBUD) needed to streamline automation of its 32 tank and pump stations.  System integrator Quality Controls LLC decided to use PLC, HMI, and SCADA products from CIMON to automate these facilities.

At each location, a CIMON Xpanel HMI lets users manage on-site pumps and tanks. Different screens allow engineers to view status and alarms, as well as diagnose and test pumps during maintenance. A CIMON PLC takes in data from sensors and outputs electrical signals to the pumps. A program automatically switches between different modes of operation, allowing for schedule-based or level-based control. The PLC also acts as a bridge between devices by storing, receiving, and sending data. When a malfunction occurs, the PLC sends a warning signal to both the SCADA program and the local HMI.

Radio transmitters were integrated into the network to overcome the immense cost and communication difficulties of laying wire through mountainous terrain. Data values are sent to a central location, then processed by the UltimateAccess SCADA application. User requests are then sent back over the radio to the corresponding PLC, which performs the desired action.

The combined usage of PLC, HMI, and SCADA technologies from CIMON will allow WBUD to more effectively manage its pump and tank stations.

FLIR Si1-LD - Industrial Acoustic Imaging Camera for Compressed Air Leak Detection

The FLIR Si1-LD is an easy-to-use acoustic imaging camera for locating and quantifying pressurized leaks in compressed air systems. This lightweight, one-handed camera is designed to help maintenance, manufacturing, and engineering professionals identify air leaks faster than with traditional methods. Built with a carefully constructed array of MEMS microphones for high sensitivity, the Si1-LD produces a precise acoustic image that visually displays ultrasonic information, even in loud, industrial environments. The acoustic image is overlaid in real time on a digital image, allowing you to accurately pinpoint the source of the sound, with onboard analytics which quantify the losses being incurred. The Si1-LD features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Transferring of images can be managed via memory stick or USB data cable. Through a regular maintenance routine, the FLIR Si1-LD can help facilities reduce their environmental impact and save money on utility bills.
