A tipping bucket shall be used to measure rainfall, and a data logger shall record the measurements. The system shall be called the Isco 676 Rain Gauge. 2) RAIN GAUGE A) The 676 shall be a tipping bucket rain gauge with an 8 inch ( 20 cm) diameter orifice. E) The bucket shall tip with every {[ 0.01 inch ( 0.25 mm)][ 0. 1 mm ( 0.004 inch)]) l of rainfall. Rainfall shall be measured with an accuracy of {[ +/- 1% at a rainfall rate of 2 inches ( 50 mm) per hour, and + 3 0/./- 4% at a rainfall rate of up to 5 inches ( 125 mm) per hour][ + /- 1. 5% at a rainfall rate of 2 inches ( 50 mm) per hour, and + 3. 5 %/ - 9% at a rainfall rate of up to 5 inches ( 125 mm) per hour])'. The rain gauge shall have a capacity of 22 inches ( 560 mm) per hour][ 15 inches ( 380 mm) per hour]) 1. C) The bearings on the tipping bucket shall be spring -loaded sapphire jewel bearings to prevent damage to the bearings and ensure consistent operation over an operating temperature range of 32 to 140 OF ( 0 to 60 ° C). D) The rain gauge shall have 3 leveling knobs and a bubble level to aid in leveling the rain gauge after it is fastened down. E) A magnetic reed switch shall provide an isolated, dry contact closure of at least 50 millisecond duration with each tip of the bucket. A 50 foot ( 15. 2 m), 2 conductor cable, and 4 pin MS connector shall provide connection to a data logger. Teledyne Isco 676 Rain Gauge / Engineering Specifications / Page 1 of 4  luawoinb3 6uuo3! UOW Molj tZO- tt 911 : o£ 4t) tZo- t t 811 rol Ieulwgns oosl au6palay auawgaelty m mmo.om F) The rain gauge shall be constructed of stainless steel, aluminum, and YdU a plastic. All metal parts shall be coated, plated, or painted. There shall be screens on all openings to prevent leaves, insects, and other debris from clogging the rain gauge. 3) DATA LOGGER A) The data logger shall be connected to a tipping bucket min gauge that tips with every 0.01 inch ( 0.25 mm) of rainfall. B) The internal data storage memory in the flow logger shall have a capacity of 230 kilobytes. Timing for the data storage shall be selectable in 1, 2, 5, 10, 15, 30, 60, or 120 minute intervals. The data shall be programmable to operate in either rollover, slate, or triggered slate mode. Triggering events in slate mode shall be selectable from level, flow rate, rainfall, and time. C) The data logger shall be programmed using a software program that shall operate on an IBM PC or compatible computer. The software shall also retrieve stored data from the data logger, and generate graphs and reports from stored data. The computer shall communicate with the data logger using a direct RS -232 connection. D) The data logger shall have optional voice messaging capabilities to dial out based on rainfall. The data logger shall call up to 5 telephone numbers with a programmable delay between each call. Acknowledgment of
