摘要
The invention relates to a method and a device for determining the volume of liquid remaining inside a flexible pouch (2) initially filled with a volume Vi of a liquid to be consumed and provided with means for dispensing the liquid to be consumed, the method comprising positioning the pouch inside a rigid envelope (6) filled with a known volume V1 of a first measuring liquid having an electrical conductivity C1, during the dispensing of a volume VA of liquid to be consumed, introducing, into the rigid envelope, the same volume of a second measuring liquid present outside the rigid envelope and having an electrical conductivity C2 different from the electrical conductivity C1, measuring the electrical conductivity CM of the mixture of the measuring liquids present inside the rigid envelope, determining the volume VA of liquid to be consumed, which has been dispensed on the basis of the measurement of the electrical conductivity CM, and calculating the volume Vr of liquid to be consumed remaining inside the pouch on the basis of the volumes Vi and VA.
