Carbon Steel 'Style P' Straight Through Flow Indicator

This Carbon Steel 'Style P' Straight Through sight flow indicator is used to check the presence of flow of a liquid in an pipeline. The indicator sight glass has a plain spout cast in the body which is ideal for visually detecting leakage or intermittent flow. It can be used in vertical or horizontal lines and is ideal as a plant safety device.

Available with flanged or screwed connections and in sizes 1/4" to 6" depending on connection.

The glass windows are held in place by stainless steel covers and screws, and sealed with PTFE gaskets, giving superior protection. For ease of maintenance the glasses can be individually removed and replaced.

For standard applications the indicator is fitted with toughened soda lime glass discs to BS3463 and rated to 16 bar.

For steam and condensate we recommend toughened borosilicate glass, while for alkaline liquids mica discs can be used to protect the glass.
