Compressively transferring type liquid feeding apparatus

Abstract

Abstract PURPOSE:To simply and economically control residual liquids in a plurality of liquid storage tanks by controlling with at least one sensor. CONSTITUTION:A pressurizing tube system B equipped with a pressurizing means and a gas exhaust tube system C equipped with on-off valves 37-46 are provided. Also, a gas introducing inlet for compressive transfer connected with the pressurizing tube system B and a gas exhaust outlet connected with the gas exhaust tube system C are provided inside liquid storage tanks 2-11 whose tops are constituted of closed containers are provided at the upper section, while a liquid discharge port connected with a liquid feeding tube system A is provided at the lower section of the inside. Further, a pressure sensor 12 is disposed in the system pressurizing tube system B or the gas exhaust tube system C. The space volume and/or residue volume in the liquid storage tanks 2-11 can be computed for the variation of sensing output from the pressure sensor 12 in an operation section 53 after starting of pressurizing by the pressurizing means or starting of pressure reducing by opening the on-off valves. As a result, residue in a number of liquid storage tanks can be controlled simply and economically.
