An Optical Sprayer Nozzle Flow Rate Sensor, Joseph S. Dvorak, Luke E. Bryant
Biosystems and Agricultural Engineering Faculty Publications
Ensuring proper flow rates from each nozzle on an agricultural sprayer has become even more important as advances continue to be made in precision application technology. In this article, we describe the structure and testing of a sensor technology based on optical cross-correlation to determine the flow rate of individual sprayer nozzles. An advantage of this technology is that it does not require that impellers or other components be placed in the flow, which could cause plugging. The only moving part in the entire system is a solenoid used to inject a tracer dye. The objective of this study was …

Water Resources Data For Nebraska Water Year 1976
Water Resources Data For Nebraska Water Year 1976
Conservation and Survey Division
Water resources data for the 1976 water year for Nebraska consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for 146 gaging stations; stage and contents for 9 lakes and reservoirs; water quality for 40 gaging stations, 18 ungaged stations, 27 partial-record flow stations, and 96 wells; and water levels for 66 observation wells. Also included are 114 crest-stage partial-record stations and 12 low-flow partialrecord stations. Additional water data were collected at various sites, not part …
