Method for conveying reducing medium from storage tank, involves detecting low liquid level in storage tank and preparing pole reversal of conveying device

摘要

The method involves detecting a low liquid level (72) in a storage tank (12), preparing a pole reversal of a conveying device (42) during positioning a vehicle and opening a dosing module (52) of a dosing system. Volumes (62) are provided, which are transferred due to the effect of the hydrostatic pressure.
