|Title:||Automatic detection of evaporation reducing monolayers||Contributor(s):||Coop, Paul A (author); Lamb, David (author); Fellows, Christopher (author) ; Bradbury, Ronald (author)||Publication Date:||2011||Handle Link:||https://hdl.handle.net/1959.11/9923||Abstract:||Mono-molecular layers, or monolayers, on the surface of water can reduce evaporation by up to 40% on small storages. Effective reduction requires the maintenance of coverage by dispensers, which must be informed by sensors capable of detecting the presence/absence of the monolayer. However, no system has yet been developed that can reliably automatically detect the presence of monolayer. Numerous detection techniques for potential field deployment, including optical and infrared reflectance, measurement of surface tension and wave damping methods were investigated. A wind assisted surface probe (WASP), based on the temperature differential between the sub-surface and volume of a small sample of periodically-entrapped water was subsequently developed. In small scale testing it has shown to be a reliable indicator of monolayer in all but very high humidities.||Publication Type:||Conference Publication||Conference Name:||Society for Engineering in Agriculture (SEAg) Conference: Diverse Challenges, Innovative Solutions, Surfers Paradise, Australia, 29th - 30th September, 2011||Conference Details:||Society for Engineering in Agriculture (SEAg) Conference: Diverse Challenges, Innovative Solutions, Surfers Paradise, Australia, 29th - 30th September, 2011||Source of Publication:||Proceedings of the Biennial Conference of the Australian Society for Engineering in Agriculture (SEAg), p. 159-168||Publisher:||Australian Society for Engineering in Agriculture||Place of Publication:||Barton, Australia||Field of Research (FOR):||020501 Classical and Physical Optics||Peer Reviewed:||Yes||HERDC Category Description:||E1 Refereed Scholarly Conference Publication||Statistics to Oct 2018:||Visitors: 709
