ABSTRACT:
A device for measuring the viscosity of the fluid flowing in a closed passage includes a rotor whose speed of rotation is directly dependent on the rate of flow of the fluid. The rotor is connected to an activatable and deactivatable brake means which has an adjustable braking force. Depending on the setting of the brake means, the brake is operative to cause a greater or smaller lag in the rotary speed of the rotor in relation to an unbraked rotor or a rotor braked with a smaller force. The measuring means is operative to determine the resultant different rotational speeds of the rotor and the different in these speeds is a measurement of viscosity.
