Brake fluid viscosity determination method in which an inductive fluid level measuring device is used to force the float into the fluid with the float velocity and coil current measured to determine the fluid viscosity

摘要

Method for determining the viscosity of brake fluid using fluid level measurement equipment used with a brake fluid reservoir. Said measurement equipment comprises a float coupled to a yoke that interacts with the coil of an electromagnet. According to the method the coil is connected to a voltage source which forces the float into the brake fluid. The average velocity of the float is determined over a measurement interval and the current strength in the (6) coil is measured at a given time point. From the two values the fluid viscosity is determined.
