Abstract (en)
[origin: EP2615309A2] The method involves attaching a flat arrangement (15) on a wall (11) of a pressure tank (10). The flat arrangement is made up of a base material provided with an electric conductor and designed to form a component of a capacitive measuring arrangement. A change of an electrical alternating field to be generated in the tank is measured by change of position of a piston (13), where the electrical alternating field is generated by the supply of electrical energy. A respective position of the piston is determined in the tank that is made of fiber-reinforced plastic material. An independent claim is also included for a device for performing a method for determining position of piston movement in a cylindrical pressure tank.
