Package goods e.g. medicated powder, amount e.g. dry weight, measuring device for blister package, has measuring unit to measure oscillation response of cavity and analysis unit to determine amount based on comparison of response with value

摘要

The device has an oscillation producing arrangement (18) for initiating a blister cavity (12) of a blister package (13) to oscillations in sound region e.g. ultrasound region. The arrangement produces the oscillations with variable frequency in variable or constant amplitude. A measuring unit (19) is provided for measuring an oscillation response of the cavity. An analysis unit (21) determines amount of package goods such as the package good weight, based on a comparison of the response with reference values. An independent claim is also included for a measuring method of measuring the amount e.g. dry weight, of package goods such as medicated powder, which is arranged in a blister cavity of a blister package.
