Abstract

In a paper or paperboard machine measurements are conducted with at least one measurement means attached to an element in the paper or paperboard machine. The measurement means has two surfaces made of electrically conductive material and has insulating material between them. The change in the capacitance between the surfaces made of conductive material is measured.
