Volume: 530-531 Monograph title: Advances in Measurements and Information Technologies Issue date: 2014 Publication year: 2014 Pages: 233-236 Language: English ISSN: 16609336 E-ISSN: 16627482 ISBN-13: 9783038350392 Document type: Conference article (CA) Conference name: 2014 International Conference on Sensors Instrument and Information Technology, ICSIIT 2014 Conference date: January 18, 2014 - January 19, 2014 Conference location: Guangzhou, China Conference code: 103218 Publisher: Trans Tech Publications Abstract: A portable digital liquid density measurement system was designed. According to Archimedes principle that a sinker's buoyant force in some liquid is related with liquid density, the system proposed converted analog signal of a pressure sensor into digital signal which can be processed by AT89C52 microcontroller using ADHX711 with high accuracy. Temperature calibration was considered in data processing, which made it possible to accurately measure liquid density at different temperatures. Experiment results show that the method proposed is superior to traditional methods.' © (2014) Trans Tech Publications, Switzerland.
