ABSTRACT:
Viscosimeter comprising a flow system for the liquid to be tested, having a narrow zone, zones for determining the pressure of the liquid to be tested located before and after the narrow zone, said zones for determining the pressure of the liquid to be tested being surrounded by tubes of a thin-walled material adapted to transfer the pressure of the liquid within the tubes to pressure transduction liquids outside each of the tubes, each of said pressure transduction liquids being in contact with one of two pressure chambers of a pressure difference recording means in such a manner that the pressures of the liquid to be tested at both sides of the narrow zone are transferred to said pressure chambers.
