<p>The invention relates to a dripping device made in order to obtain an adequate dripping interval between serial drips, the device being used for determining the resistance index of the surface-leakage flows. According to the invention, the device consists of a cylindrical recipient (), wherein a sample liquid () is stored, at the lower side, the said recipient being provided with a dripping orifice () obturated by means of a rod () with conical termination () actuated by means of a linear guide made of a plate () and some elements (), the plate () being coupled to the axle () of the piezoelectric motor () connected to a computer () and the vertical movement of the rod () of micrometrical precision, allowing the opening of the orifice () and the elimination of a drip, thus resulting in a fine adjustment for the dripping interval.</p> |
