(54) U-tube rheometer for the dynamic measurement of elasticity


(57) This invention relates to a rheometer of U-tube type for measuring rheological properties of gel or other materials; and the method for the said measurement, it comprises of a U-shape channel where the test sample is contained; means for creating a desired air pressure applied to the sample from one side of the U-tube and means for monitoring the change in pressure in the enclosed chamber at the other side of the U-tube from which the sample volume displacement can be calculated. The method allows rigidity modulus measurement implemented on a very weak gel at controllable small disturbance to the sample. The rheometer is automatic and computerized capable of both dynamic and static measurements at controlled thermostatic environment.
