⚫ Most liquid and semi-liquid products are filled by one of two major methods: volumetric, or constant level filling. ⚫ In volumetric filling the amount of product is premeasured so that each container has the same volume of product. ⚫ Constant level filling techniques fill each container to the same level, so it is frequently called the “fill-to-a-level” method.

Liquid Filling 3. Use of Filling Machines ⚫ Volumetric filling is particularly appropriate for applications in the pharmaceutical industry where it is important that each container is accurately filled with a specific volume of product. ⚫ Constant level filling is used with see-through bottles in which it is important that all of the bottles in a display appear to be filled to the same level, although the bottles may not be exactly the same size and the volumes may be slightly different
