<p>A quantity meter (10) for determining the quantity of liquid flowing through a line (4; 6) is provided with at least two electrically conducting elements (12; 12A, 12B, 12C), arranged in the line (4; 6) at some distance from each other, and being in communication with an electronic circuit (14). In this electronic circuit, on the basis of the electric conductivity (14) of the liquid measured by the electronic circuit, the length of the interval of time during which this conductivity is measured, the distance between the electrically conducting elements in the line (4; 6), the rate of flow of the liquid and the specific electric resistance, there is determined the quantity of liquid flowed through. <IMAGE></p> |
