Sanitary Sight Flow Indicators
|
|
Penberthy's Sanitary Sight Flow Indicators have been designed to enhance the visibility of the process
media as it flows past the glass windows. The glass windows assist the operations manager by creating a window to the process
volumes, directions and reactions without interrupting the process flow. The process flow stream can be monitored in may orientations.
Penberthy models are available in a variety of sizes.
System Description
Penberthy's Sanitary Sight Flow Indicators consist of six basic components. Each component may vary slightly, depending on the
desired physical and mechanical properties for the indicators.
|
-
Body (sanitary cross) - provides in-line attachment capability for the Sight Flow
Indicator.
-
Glass - the glass discs are installed to provide the window of observation of
the media passing through the body.
-
Gaskets - the gaskets are compressed by the clamps to tightly seal the gap between
the body and the glass, and to prevent leaking.
-
Cushions - the cushions are compressed by the clamps to tightly seal the gap between
the glass and the cover.
-
Cover - supplies the compression load to the gaskets, glass and cushion to seal
all gaps when the clamp is tightened.
-
Clamp - grooved clamp that draws two flanged ends together when tightened. One
and two hinged clamps are available.
