MEASURING METHOD AND MEASURING STATION TO DETERMINE THE VOLUME OF LIQUID PRODUCT CONTAINED IN A DISPOSABLE CARTRIDGE FOR SMOKING ARTICLES

摘要

A measuring method and a measuring station (S4) to determine the volume of liquid product (4) contained in a disposable cartridge (1) for smoking articles; the measuring station (S4) has: a measuring chamber (13) which is designed to be sealed in a tight manner and is designed to house the cartridge (1) which contains a dose of liquid product (4) with an unknown volume and has an open upper end (3); an actuator (18), which is designed to change the volume of the measuring chamber (13); a sensor (19, 20), which is designed to determine the volume variation (ΔV) of the measuring chamber (13) and/or the pressure variation (ΔΡ) in the measuring chamber (13) due to the volume change; and a control unit (21), which is designed to determine the volume of the dose of liquid product (4) contained in the cartridge (1) based on the volume variation (ΔV) and/or on the pressure variation (ΔΡ) due to the volume change.
