Full View Sight Flow Indicators are assembled with tubular Borosilicate glass. These indicators
are simple in construction and used for checking flow from any direction where various values
or pump might have to be operated based on the flow in the line. These are recommended
where there is no mechanical strain in the pipe line. Inside diameter of the glass tube is as
large as or larger than the nominal size of the flow indicators. It is designed for only a
negligible pressure drop.
