Accuracy better than +\/\u22120.5% in density is demonstrated over a range of temperatures (50\u2009\u00b0C\u2013150\u2009\u00b0C) and pressures (150\u201315\u2009000 psi) by prior calibration with air and water. The flexibility of the tubing facilitates use of a novel actuation and detection system that greatly simplifies the fabrication. Two simple and automated calibration methods are discussed using measurements performed with an evacuated and a water-filled tube. Measurements show that the effective spring constant of the tube is strongly affected by temperature and is largely insensitive to pressure. The tube volume, on the other hand, is strongly affected by pressure.<\/jats:p>","DOI":"10.1063\/1.3226668","type":"journal-article","created":{"date-parts":[[2009,10,8]],"date-time":"2009-10-08T23:55:00Z","timestamp":1255046100000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":9,"title":["A microfluidic oscillating tube densitometer"],"prefix":"10.1063","volume":"80","author":[{"given":"Chlo\u00e9 Marion","family":"Col\u00e9ou","sequence":"first","affiliation":[{"name":"Schlumberger-Doll Research , 1 Hampshire Street, Cambridge, Massachusetts 02139, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip","family":"Dryden","sequence":"additional","affiliation":[{"name":"Schlumberger-Doll Research , 1 Hampshire Street, Cambridge, Massachusetts 02139, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Harrison","sequence":"additional","affiliation":[{"name":"Schlumberger-Doll Research , 1 Hampshire Street, Cambridge, Massachusetts 02139, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2009,10,8]]},"reference":[{"key":"2023070403194036300_c1","year":"2006"},{"key":"2023070403194036300_c2","volume-title":"The Properties of Petroleum Fluids","year":"1990","edition":"2nd ed."},{"key":"2023070403194036300_c3","first-page":"302","volume-title":"SPWLA 45th Annual Logging Symposium","year":"2005"},{"key":"2023070403194036300_c4","doi-asserted-by":"publisher","first-page":"179","DOI":"10.1007\/BF01448220","volume":"17","year":"1996","journal-title":"Int.
