摘要

Method and system for determining the amount of liquid in a vessel for inventory taking. The amount of liquid is determined from the total volume of the vessel and the volume of the empty space in the vessel. An reference vessel is hermetically connected with the vessel. The volume of the empty space is determined from the difference in air pressure before and after air is forced into the vessel. The system comprises a device for measuring a volume of a vessel, the device comprising a reference vessel with known pressure, a connector for connecting the reference vessel with the vessel and a pressure sensor for measuring pressure in connected vessels. The system comprises a measuring head, comprising a reader for reading the RFID tag on the vessel: The system has a communication module for forwarding the measurement data to the cash register and warehouse management software.
