The software shall use pull -down menus and pop -up windows, and shall include a menu bar, toolbars, workspace, window, and status bar. C) The software shall communicate with 2100 Flow Modules over a direct RS -232 connection at 38400 bps or at 19200 bps for a wireless connection, or using a 56k telephone modem, or using a digital cellular modem. The software shall communicate with 676 Logging Rain Gauges and 4100 Series Flow Loggers over a direct RS -232 connection at 9600 bps, or using a 2400 bps Hayes compatible modem with voice messaging , or using a 19200 or 9600 bps digital cellular modem2. The software shall communicate with 4200 Series Flow Meters over a direct RS -232 connection at 9600 bps, or using a 2400 bps Hayes compatible telephone modem with voice messaging', or using a 19200 or 9600 bps digital cellular modem'. The software shall communicate with the Avalanche and 6700 Series Samplers with 700 Series Modules over a direct RS -232 connection at 9600 bps, or using a 2400 bps Hayes compatible modem with voice messaging , or using a 19200 or 9600 bps digital cellular modem'. The software shall communicate with 675 Logging Rain Gauges and 581 Rapid Transfer Devices over a direct RS -232 connection at 9600 bps. D) The software shall store all data in an industry standard Microsoft Access or enterprise database. All sites and their associated data sets, graphs and tables, and schedules shall be displayed in a workspace. The user shall have the capability to create folders to organize the workspace. E) The software shall include support for an enterprise database, Web UI, and pushed data to server. Refer to 3) ENTERPRISE DATABASE.

G) The software shall be provided on a CD. A separate included CD shall contain a program that demonstrates the features of the software, and a sample database with sample data, graphs, and tables. 2) SITE SETUP AND DATA RETRIEVAL The software shall allow the user to specify whether or not the instrument to which it is to be connected has been moved to a new site. If so, the software shall allow the user to enter a new site time and clear the data storage in the instrument. A) 4100 SERIES FLOW LOGGERS, 4200 SERIES FLOW METERS, 6700 SERIES SAMPLERS WITH 700 SERIES MODULES, 675 and 676 LOGGING RAIN GAUGES, AND 581 RAPID TRANSFER DEVICES i) Basic Information Upon connection to a flow meter, the software shall display the site name, model number, sensor type, flow conversion, software revision, instrument ID, instrument date and time, and communication setup. The software shall also display the type, voltage, and remaining capacity of the battery for 4100 Series Flow Loggers, and the battery voltage for 4200 Series Flow Meters. ii) Measurements 1) The software shall display all available parameters measured by the system, which includes but is not limited to level, velocity, flow rate, total flow pH, dissolved oxygen, conductivity, and temperature, voltage, and the sampler enable status. The software shall set the flow stream level in the flow meter. The software shall also display the sampler enabled flow for 4200 Series Flow Meters, and the positive and negative flow for a 4250 Area Velocity Flow Meter. 2) The software shall display the most recently retrieved measurements from all sites of interest in a single window. 3) The software shall include diagnostics to display the signal strength and spectrum strength from a 4150 Area Velocity Flow Logger and 4250 Area Velocity Flow Meter, and the signal strength from a 4110 Ultrasonic Flow Logger and 4210 Ultrasonic Flow Meter. The diagnostics shall also display status messages from a 4200 Series Flow Meter for power failed, paper out, printer jammed, and printer power. iii) Site Setup 1) The software shall set the site name, instrument date and time, and password for each flow meter, and zero the totalizer in the flow meter. The software shall set the variable blanking distance for a 4110 Ultrasonic Flow Logger and 4210 Ultrasonic Flow Meter. The software shall set the Teledyne Isco Flowlink Professional Softwarefor Windows / Engineering Specifications Page 2 of14 uuawdinb3 6uijouuoW mold lZ0- tt 911 : Ofbl) LZo- ti, 911 iol lenlwgng oast au6p0l0l .3uawgaeutl y ev 0 a a zero level offset and the set flow rate to zero if no velocity data setting for m o. a 4150 Area Velocity Flow Logger and 4250 Area Velocity Flow Meter, and the minimum depth for velocity measurement for a 4150 Area Velocity Flow Logger and 4250 Area Velocity Flow Meter with a Standard Area Velocity Sensor. 2) The software shall display and save to a file the program, two summary reports, and history report from a 4200 Series Flow Meter. iv) Data Storage The software shall divide the memory in a 4100 Series Flow Logger into up to 6 memory partitions, and shall divide the memory in a 4200 Series Flow Meter into up to 12 memory partitions. Each partition shall store level, velocity, flow rate, rainfall, pH, dissolved oxygen, conductivity, temperature, or sampler data. The interval for storing data in each partition other than sampler partitions shall be selectable from 1, 2, 5, 10, 15, 30, 60, or 120 minutes, and the time span for each partition shall be entered in days and hours. For 6700 Series sampler partitions, the number of samples shall be entered. Each partition shall operate in either rollover, slate, or triggered slate mode. The size, data storage interval, and data storage mode of each memory partition shall not have to be the same. The reading type, reading interval, time span, and recording mode for each partition shall be visible even when the computer is not connected to the flow meter. 1) In rollover mode, readings shall be stored in memory continuously. When the memory is full, the oldest reading shall be replaced by the newest reading. 2) In slate mode, readings shall be stored until the memory is full, at which time storage shall stop. The memory shall hold these readings until it is restarted. 3) In triggered slate mode, the memory shall operate as a rollover partition until a triggering event occurs. Once the triggering event occurs, the memory shall operate as a slate only partition and store readings until it is full. The memory shall hold these readings until it is restarted. The triggering event shall be an AND /OR combination of up to four conditions, where each condition shall be either level, velocity, flow rate, volume, rainfall, pH, dissolved oxygen, conductivity, temperature, or time. Each condition other than time shall be either greater than or equal to a set point, less than or equal to a set point, or a rate of change over a time period. A duration operator shall be available to modify the condition. A time condition shall include up to four start and stop time periods, where each time period shall be either daily, weekly, Monday through Friday, or a specific time. A NOT operator shall be available to modify any condition other than time. Parentheses shall be available to group conditions. Teledyne Isco Flowlink Professional Softwarefor 11rndows / Engineering
