Each total flow calculation shall accumulate either net, positive, or negative total flow with user- selectable resolution. L i) For level -to -area conversions, the flow module shall convert measured liquid level readings into the area of the flow using internal conversion algorithms. The flow module shall contain conversion information for round, U- shaped, rectangular trapezoidal and elliptical channels. The flow module shall accept a silt level measurement and adjust the area of the flow appropriately. The flow module shall also accept up to 50 level- area points. ii) For level -to -flow rate conversions, measured liquid level readings shall be converted into corresponding flow rate readings using internal conversion algorithms. The flow module shall accept conversion information for V -notch weirs, rectangular weirs with and without end contractions, Cipolletti weirs, Isco Flow Metering Inserts, and Thel -Mar Weirs, and Parshall, Palmer - Bowlus, Leopold- Lagco, trapezoidal, H, HS, and HL flumes. For monitoring in applications using the Manning formula in round, U- shaped, rectangular, and trapezoidal channels, the flow module shall accept information for channel configuration and size, and slope and roughness coefficient. The flow module shall accept up to 50 level -flow rate data points. The flow module shall accept a two -term, level -flow rate polynomial equation. C) The flow module shall be capable of pacing an Isco wastewater sampler. D) The flow module shall have the capability of measuring and storing the battery voltage. E) The internal data storage memory in the flow module shall have a capacity of 395, 000 bytes, equal to up to 79, 000 readings, equal to over 270 days of level and velocity readings at 15 minute intervals plus total flow and input voltage readings at 24 hour intervals. The flow module shall store data in rollover mode. The flow module shall be capable of storing level, velocity, flow rate, flow rate 2, total flow, total flow 2, and input voltage data. The data storage interval for each type of data shall be individually selectable from OFF, 15 or 30 seconds, 1, 2, 5, 15, or 30 minutes, or 1, 2, 4, 12, or 24 hours. The flow module shall be capable of variable -rate data storage, with the data storage interval changing based on level, velocity, flow rate, flow rate 2, total flow, total flow 2, or input voltage. It shall be possible to change the data storage setup for any data type at any time without disrupting the data storage of any other data types. It shall be possible to delete all data stored in the data storage memory. When reset, the flow module shall automatically revert to default settings, with level, velocity, and flow rate stored at 15 minute intervals, and total flow and input voltage stored at 24 hour intervals. The flow module shall store signal strength and spectrum strength diagnostics from the last 10 valid and the last 10 invalid velocity measurements. F) The flow module shall be programmed using a software program that shall operate on an IBM PC or compatible computer. The software shall also retrieve Teledyne Isco 2150 Area Velocity Flow Module / Engineering Specifications Page 3 of 7  juawdinb3 5uu0uu0W mold W- I L 911 : 0CV0 iZo- I l 911 jol Iell! wgns oosl auRpalal guawgaeliV m m a bY stored data from the flow module, and generate graphs and reports from stored data. The computer shall communicate with the flow module using a direct RS- am 232 connection at 38,400 baud. Connection to the flow module shall be made with a cable with a push -on, quick -connect connector that can be easily connected and removed in the field. If multiple flow modules are stacked and/or interconnected, a single connection between the computer and any one ofthe flow modules shall be capable of programming and retrieving stored data from all of the flow modules. G) The flow module shall contain 2 non -volatile, programmable Flash memories, one for the program memory and one for the user program and the stored data. The program memory shall be capable ofbeing updated via the serial port on the flow module without opening the enclosure. The flow module shall retain the user program and all stored data during program memory updates. H) The flow module shall be equipped with modbus communications capabilities, independent of Flowlink, enabling the data to be linked to monitoring and/ or process control systems and software. n The flow module shall be capable ofbeing configured identically to the configuration of a module it is replacing in the field. l) The flow module shall be powered by 12 VDC supplied by one or more stacked and/ or interconnected battery modules, I OOmA typical, 1 mA standby. Typical battery life for one flow module with 15 minute reading intervals and one battery module with two 6 volt alkaline lantern batteries shall be 15 months. The flow module shall have the capability of measuring and storing the input voltage from the battery module. K) The flow module shall be housed in a rugged, permanently sealed, submersible, watertight, dust -tight, corrosion resistant ( self -certified NEMA 4X, 6P, and IP68) enclosure. All electrical connections within the flow module shall be soldered, or shall be pin -and -socket connections that are held in place by the flow module enclosure itself The flow module shall not contain wiring harnesses that can be removed without a soldering iron. The flow module shall include a carrying handle that shall be held between the flow module and the battery module, or between two flow modules. The carrying handle shall include a suspension strap that can be looped around a manhole rung or other attachment point while the user retains hold of the carrying handle. The flow module shall include an LED that is visible from outside the flow module. The LED shall allow individual modules to be identified when multiple flow modules are stacked and/ or interconnected. The LED shall also flesh every 15 seconds for 5 minutes after a computer is disconnected from the flow module. The flow module shall be CE marked. L) The flow module shall have an operating and storage temperature of -40 to 140 OF ( - 40 to 60 oq.
