ABSTRACT:
The invention relates to a manometer with a housing, a connecting piece rigidly connected to the housing, a bourdon tube arranged in the housing, a viewing glass fixed on the housing, and a pointer, which can rotate on the inside of the viewing glass and which is engaged with a free end of the bourdon tube, wherein the housing has on its top side a connecting piece that is bent inwardly for connecting to the viewing glass. To simplify the assembly, several cutouts distributed over the periphery are arranged in the connecting piece of the housing for engagement of an assembly tool, wherein the housing is connected to the connecting piece with a positive fit.
