<p>A method of determining the viscosity of a sample fluid (11) relative to that of a reference fluid (10), characterised by causing alternate flows of the sample fluid (11) and the reference fluid (10) through viscosity-sensitive means (13, 45), alternately employing a common sensor (14), in synchronism with said alternate flows, to effect measurements of a parameter related to the respective flows through the viscosity-sensitive means (13, 45); and comparing said measurements.</p> |
