ABSTRACT:
A capillary bridge viscometer is disclosed for measuring the relative viscosity of a solute in a solvent. The bridge contains two (2) fluid flow circuits. One circuit contains two (2) capillaries in series. The second circuit contains two (2) capillaries in series with a valve and an associated liquid reservoir positioned intermediate of the capillaries. A common feed line feeds a first liquid to both fluid flow circuits. With the valve set in one operating position, the first liquid flows through all four (4) capillaries and no pressure differential is established across the bridge. With the valve set in a second operating position, the first liquid exiting the first capillary of the second fluid flow circuit flows into the liquid reservoir and displaces a second liquid stored therein which then flows through the second capillary of the second fluid flow circuit. A differential pressure is established across the bridge which is a function of the viscosity of the second liquid.
