The transfer system consists of a variable speed electricallydriven pumping unit (110) that increases the pressure of the liquid from the pressure in the mobile tanker to the pressure in the storage tank, connected to a tanker outlet (201) and storage tank feed pipe (202), a pressure sensor (114) and a control box (130). The control box has a frequency regulator (132) between the pressure sensor and pumping unit output, adjusting its speed of rotation with the variation in feed current frequency in accordance with the signal from the pressure sensor. |
