1. Circuit for the measurement of the coefficient of dynamic viscosity of liquids, containing electrical amplifiers and hydraulic resistors and condensers, characterized in that it contains a hydraulic condenser (4), whose hydraulic chamber (3) is connected to the measurement channel of a hydraulic resistor (2), while the free end of the elastic element (5) of the hydraulic condenser (4) is connected to a converter (6) which converts the deflection of the elastic element into an electrical signal, and the output of that converter (6) is connected successively via an electrical differentiating circuit (7) and an electrical integrating circuit (8) to the input of an electric comparator (9) with zone of hysteresis, this being connected to the input of an electromechanical converter (10), preferably electromagnetic, mechanically coupled to the elastic element (5) of the hydraulic condenser (4).<IMAGE>
