Method for manufacturing a measuring apparatus for determining and/or monitoring at least one process variable. At least one sensor element is inserted into an at least partially pot-shaped mold, and the mold is at least partially filled with a casting material composed at least of a first component and a second component. The mold is filled with the casting material, at least partially, with at least the following steps at least one predeterminable amount of the first component of the casting material is charged into the mold; at least one predeterminable amount of the second component of the casting material is charged into the mold; and the mold is vibrated and/or caused to oscillate with a predeterminable frequency. Furthermore, a method for filling an at least partially pot-shaped mold is disclosed.
