The threaded connection rates highly with its low installation geometry and simple assembly, and is therefore ideal for pipelines with a small cross-section.

The flange connection can serve as a universal solution. Flange-mounting is used, so that no turning or screwing movement is needed with the measuring instrument. This protects electrical connection cables and any capillaries. It is also the first choice with highly viscous or flocculent media.

Both connection types are frequently used in the oil and gas industries and also in the chemical industry.
The sterile connection is used wherever high hygienic standards are demanded.
The keywords here are: “Hygienic design”, “3-A” or also “EHEDG”
An absolute requirement is that the connection can be cleaned quickly and without leaving residues. As a sterile fitting, the diaphragm seal features a flush diaphragm.
