ABSTRACT:
A method and apparatus for measuring the viscosity of a sample solution which comprises an input tube for transporting a sample solution flow towards a splitter for diverting input flow into two distinct flow streams where three capillary tubes are located in the two flow streams placed downstream from the flow splitter, where each flow stream has one or two capillary tubes, a delay volume, and a flow through transducer having hydraulic connections placed in one stream or in two streams used for measuring the pressure difference across the capillary tubes; where the method of using such viscometer can enhance the viscometer output by effecting compensation for non-linearity and different fluidic properties in pressure transducers to provide viscometer detector outputs independent of both low and high frequency flow components.
