DG04 Sight flow indicator for wafer mounting

Model series DG04 sight glasses are distinguished by their rugged construction and wide range of applications. They feature 30, 50 or 100 mm long transparent cylinders made of acrylic or borosilicate glass with very high wall thickness. These cylinders are intended to be clamped between two existing flanges. Their dimensions match those of the sealing face on the raised area of the flange. This sizing makes support from a separate metal housing unnecessary.

In addition, this design allows the flow to be viewed and monitored from any direction. The flange screws provide additional protection against mechanical damage.

The sight glass has no dead spaces, so that it can be flushed / cleaned together with the pipeline when changing products.

There are no deposits in the sight glass when the pipeline is drained, because the inner diameter of the sight glass corresponds to the inner diamater of the pipeline. The DG04 are therefore also ideally suited for sterile and antiseptide applications.

The sight glasses can be used in almost all pipelines. In the borosilicate glass version, the units can be used for chemically very aggressive media. They are insensitive to contamination because the inner surface is always rinsed by the flowing medium.

In particular, the larger nominal sizes are very cost effective splutions since they require the transparent cylinder and no metal housing with flanges.
