Claims (4)

1. Способ измерения вязкости жидкости (1), в котором вращающуюся измерительную головку (3) вводят в жидкость (1) и считывают вращающий момент (М), действующий на измерительную головку (3), отличающийся тем, что измерительная головка (3) вращается по существу с постоянной скоростью (Ω), тем, что вращающий момент (М) считывают на двух глубинах введения (h1, h2) измерительной головки (3) в жидкость (1), и тем, что вязкость (n) жидкости (1) вычисляют по формуле
Figure 00000001

где М - вращающий момент, действующий на измерительную головку;
С - постоянная, содержащая количество оборотов измерительной головки, а также ее диаметр;
h - текущая глубина введения;
n - вязкость жидкости;
δh - изменение глубины введения.1. A method of measuring the viscosity of a liquid (1), in which a rotating measuring head (3) is introduced into the liquid (1) and the torque (M) acting on the measuring head (3) is read, characterized in that the measuring head (3) rotates essentially at a constant speed (Ω), in that the torque (M) is read at two depths of insertion (h 1 , h 2 ) of the measuring head (3) into the liquid (1), and in that the viscosity (n) of the liquid ( 1) calculated by the formula
Figure 00000001

where M is the torque acting on the measuring head;
C is a constant containing the number of revolutions of the measuring head, as well as its diameter;
h is the current depth of introduction;
n is the viscosity of the liquid;
δh is the change in the depth of administration. 2. Способ по п.1, отличающийся тем, что измерительную головку (3) вводят в жидкость (1) по существу с постоянной скоростью. 2. The method according to claim 1, characterized in that the measuring head (3) is introduced into the liquid (1) at a substantially constant speed. 3. Вискозиметр для осуществления способа по п.1 или 2, содержащий приводной двигатель (7), который снабжен датчиком крутящего момента (9) и приспособлен для вращения измерительной головки (3), которая вводится в жидкость (1), отличающийся тем, что измерительная головка (3) является круглоцилиндрической и имеет постоянный диаметр, и тем, что измерительная головка (3) приспособлена для вращения относительно ее оси цилиндра, а также к введению в жидкость (1) вдоль упомянутой оси по меньшей мере на две произвольные глубины введения. 3. A viscometer for implementing the method according to claim 1 or 2, comprising a drive motor (7), which is equipped with a torque sensor (9) and is adapted to rotate the measuring head (3), which is introduced into the liquid (1), characterized in that the measuring head (3) is circular-cylindrical and has a constant diameter, and the fact that the measuring head (3) is adapted to rotate about its axis of the cylinder, and also to introduce at least two arbitrary insertion depths into the liquid (1) along said axis. 4. Вискозиметр по п. 3, отличающийся тем, что свободный конец измерительной головки имеет закругленную или коническую форму. 4. The viscometer according to claim 3, characterized in that the free end of the measuring head has a rounded or conical shape.
