Abstract

An operating fluid tank includes a capacitor. The capacitor includes a first electrode and a second electrode. Between the first electrode and the second electrode, a clearance is formed which is fluid-connected to an operating fluid tank interior. The fluid tank also includes an evaluator electrically connected to the capacitor for determining a capacity of the capacitor by means of measurement signals determined by the capacitor. The first electrode and the second electrode include an electrically conductive plastic material.
