<p>The apparatus is for dosing a liquid contained in a vat (2) with a solution contained in a reservoir (1). A conduit (8) connects the lower part of reservoir (1) to an intermediary dosage station (4). A valve (9) is incorporated in the conduit (8). Prior to entry into station (4) the conduit (8) merges with conduit (5) integral at its upper end, with a three way valve (6). A conduit (7) connects the output of station (4) to the vat (2). The three way valve enables atmospheric pressure or pressurised gas to be applied to the conduit transferal system so as to effect dosage of the vat (2).</p> |
