Problems solved by technology

However, high-precision measurements by scales require just enough time for the measurements to stabilize, typically greater than a minute
However, such long measuring times impede the production process in the online control of the filling process and accordingly do not meet industrial requirements

Embodiment Construction

[0028] It is known that terahertz waves can pass through most plastic materials, paper, ceramics and other non-metallic substances, especially also through common packaging materials and common packaged substances (powders and liquids), that is, These substances are said to be transparent to terahertz-radiation.

[0029] It is also known that each electromagnetic wave requires a certain runtime t ("Runtime") when passing through a transparent medium, which is multiplied by the calculated index ("Refractive Index") n and the corresponding geometric length L of the transparent medium proportional. The product of the calculation index n and the geometric length L is also called the optical length. The running time t is correspondingly calculated by the following formula:

[0030] t = L · n c ,

[0031] Among them, "c" represents the speed of light in vacuum,...

Abstract

The present invention relates to a method for determining a quantity of a free-flowing substance metered into a body that is to be filled, wherein a terahertz impulse is generated that passes through the body to be filled and through the metered amount of the free-flowing substance received in said body, and wherein the metered quantity of the free-flowing substance is determined from a propagation time of the terahertz impulse.

Description

technical field [0001] The invention relates to a method for determining the quantity (mass or volume) of a flowable substance to be dosed into a body to be filled. Background technique [0002] Especially in production lines where objects are filled with loose materials (such as powders) or with liquids (such as pharmaceutical capsules), it is necessary to determine the substances respectively filled into the objects to be filled without interfering with the objects to be filled amount. In pharmaceutical devices for microdosing powders or liquids into capsules, it is especially necessary to determine the respectively dosed quantity in-line and without disturbance after the capsule has been filled or after the capsule has been closed. Precisely in such microdosing processes in the pharmaceutical industry it is necessary to determine the dosed quantities very precisely. [0003] DE 100 01 068 C1 discloses a device for dosing and expelling powders into hard gelatin capsules,...
