2 Maximum allowable level: 20 feet or greater 4. 1. 3 Minimum accuracy: 0.010 feet / foot for levels of 0. 03 feet to 5 feet ± 0. 012 feet / foot for levels > 5 feet 4. l.4 Temperature coefficient: 0.0035 feet / degree F over range of 320 to 122° F 4. 1. 5 Long term drift shall not exceed 0.03 feet. 4. 2 A hydrophobic filter shall be used to protect the level sensor from atmospheric moisture. The level sensor shall be factory calibrated from 0 —10 feet at 1 foot increments to ensure linearity throughout measurement range. To ensure accuracy during surcharge events, field span calibration will not be required or accepted. 4. 3 The sensor span shall be factory calibrated across the specified temperature range and shall not require temperature stabilization time. The sensor shall be temperature characterized across the entire temperature range of the transducer to ensure long tern stability, even in dry flow applications. 4.4 Sensor materials exposed to the flow stream shall be epoxy, stainless steel, polyvinyl chloride (PVC), or chlorinated polyvinyl chloride (CPVC). 5. OPERATING TEMPERATURE RANGE The flow monitor shall be capable of operating within a temperature range of 00 to 140 °F for a prolonged period without incidence of failure. Submerged sensors shall be capable of operating within a temperature range of 320 to 140 °F for a prolonged period without incidence of failure.

DATA STORAGE Y aN 6. 1 The flow monitor shall store, at a minimum, 60 days of velocity and level data collected at 15 minute intervals, with the ability for the monitor to automatically adjust its data recording intervals to as frequent as 15 seconds, based on one of several conditions, including level, velocity, flow rate and input voltage. This is necessary to ensure that more readings are taken during storm event flows where precise data is critical. 6. 2 Data stored shall include, at a minimum, depth of flow, velocity, and flow rate. 6. 3 Data shall be stored in non- volatile memory so that no data is lost when programs are changed or glitches occur in the monitor. If firmware changes are made, the monitor shall maintain all its data, programming and calibration information. 6.4 When data storage is full, new data shall overwrite the oldest stored data. 7. BATTERIES 7. 1 The flow monitor shall be powered by standard ( 18 amp / hour) or commercial 26 amp / hour) 6 Volt alkaline lantern batteries or by special batteries with the following consideration: 7. 1. 1 Regardless of the battery type, one battery or one pair of batteries installed simultaneously, whichever is required to power the monitor shall have sufficient capacity to power the monitor for the collection of data at 15 minute intervals for 60 days. 8. WIRELESS COMMUNICATIONS & SOFTWARE 8. 1 Flow monitor setup shall be accomplished via serial connection to a PC or remotely via cellular communications. 8. 2 The software provided for data retrieval and monitor setup shall, at a minimum, have the following capabilities: 8. 2. 1 Calculate and display average, max, and min flows 8.2.2 Readily display velocity, depth, and flow rate data in hydrographs, scatter graphs and tubular format 8. 2.3 Real -time readings occur automatically once connected and are updated within 15 seconds typically. 8. 2.4 Software shall allow for immediate/real time graphics in order to field crews to easily determine if sensor or system needs service. 8. 2.5 Can import and plot other monitor manufacturer' s data, such as, rain data, etc. 8.2. 6 Multiple hydrographs can be shown on one chart. 8.2. 7 Dry weather and wet weather hydrographs; can be shown on one chart, in addition to, plotting the difference of wet and dry weather flows. 8.2.8 Is compatible with all current Microsoft PC operating systems 8. 2.9 Easily export flow monitoring data to MS Excel Page 18 of 27  tuawdlnb3 6uuotluoly Hold LZO- tt ell: OEVt) tuawnoop pl9 lZ0- 1i l ell auawyoeuy aa oe 8. 2. 10 Graphs or tables may be saved as bitmap or jpeg files and can be easily A exported, a 8. 3 The software provided with the monitors shall be licensed for use on two desktop computers and an unlimited number of laptop computers. Upon purchasing the software, the City shall have unlimited use of the software, forever, without any requirement, whatsoever, to purchase annual licenses, maintenance plans, technical support or use authorization codes. Once purchased, the software shall be the property of the City. Technical support shall be famished via email, phone, or mail for as long as needed at no additional cost. The City shall receive upgrades to the software as is necessary for the software to remain compatible with future Microsoft operating systems. There shall be no cost for minor software upgrades or upgrades to maintain compatibility with Microsoft operating systems. 8. 4 Four copies of software user' s manuals shall be furnished with the software. 9. SENSOR MOUNTING HARDWARE 9. 1 Sensor mounting rings shall be fabricated in 316 stainless steel and designed to hold sensors rigid in the flow. Rings shall come with all hardware necessary to mount the sensor in the pipe. 9.2 The unit bid price for each mounting ring assembly shall include the ring, extensions, sensor mounts, and all other hardware necessary to properly mount the sensor in the pipe of the identified diameter. 30. WARRANTY 10. 1 The warranties below shall apply to the original monitors, sensors, mounting rings, cables, and other ancillary items related thereto. The warranties shall also apply to any purchase of the aforementioned items in the future. These warranties shall be provided by the manufacturer of the flow monitoring equipment. 102 The flow monitor and all associated accessories, except flow sensors, shall have a 12 month warranty covering parts, labor, and shipping from the date of installation. Any flow monitor component or accessory that fails under normal service to meet the manufacturer' s specifications within a 12 month period shall be repaired or replaced by the manufacturer at no expense to the City. 10.3 The velocity and depth sensors shall have a 24 month warranty that covers parts, labor, and shipping costs from the date of purchase. Any sensor that fails under normal service to meet the manufacturer' s performance specifications within a 24 month period shall be repaired or replaced by the manufacturer at no expense to the City. 10.4 Warranty service in accordance with Item 1 above shall be provided when damage to monitors, sensors, etc. is caused by hydrogen sulfide.
