Installation Rings and Mounting Hardware Mounting hardware will be provided to enable the complete installation of each unit and sensors in addition to 5 additional spare rings. 4. Software The Intelliflow system is designed to interact with two different software systems, which are described below: Intelliflow On -Linen': Intelliflow On -Line is software that resides in the meter's memory and is used to communicate with the meter. This feature allows a user to utilize any PC equipped with Microsoft Windows 95 Dial -Up Networking software to perform configuration, hardware diagnostics and flow data retrieval functions. In other words, you only need a computer with Windows 95 to collect data from an Intelliflow meter because the Intelliflow comes standard with its own communications software. Communication can be established with the meter in two different ways. If telephone service is desirable, the user may communicate with the Intelliflow from a remote location using a computer equipped with a modem. Otherwise, users must communicate with the meter on-site directly using a serial communication cable. Once this serial connection is established with a laptop computer, the user would establish communication with the meter through Dial- Up Networking in Windows 95. Intelliflow On -Line allows users to change site-specific information, check built- in diagnostics, collect data or access an on-line user's manual. ProfileTM Software: Profile software converts the data collected by Intelliflow On -Line into collection system information. Profile allows users to perform data management, edit data, develop various reports and conduct analysis. Profile uses open database architecture which makes it easy to import and export flow data into various reports. Profile's graphical user interface and Windows-based functionality make it more intuitive and easier to use. The Central Station data analysis software will have the following minimum requirements. A software user's guide will be provided in hard copy format and as part of the installation CD.
