DEVICE FOR THE REMOVAL OF LIQUID SAMPLES FROM THE STORAGE TANK

摘要

A device is described for the removal of liquid samples from a storage tank, in particular for the removal of mineral oil samples and mineral oil-product samples, in order to verify their properties. The technical result which can be achieved with the invention is a simpler sample removal from the planes, from which samples are to be removed, and a greater correlation of the properties of each sample with the properties of the product at the corresponding plane of the sample removal. The technical result is achieved by the use of a vacuum pump which is connected to a collecting pipe at the top, to a removal valve at the bottom and to the lower part of the storage tank via a return valve and a return tubular connection piece.
