Penberthy Dual-Window Sight Flow Indicators

Flow Factor offers Flow Site Windows by Penberthy.
Flow Sites indicate flow via a glass window and can be offered with a flapper, rotator, drip tube or gaseous.

In high traffic or confined areas, add protection to your pipeline system.

Dual-Window Sight Flow Indicators provide two glass discs on each side, so that if either glass should fail for any reason, the other window can temporarily withstand pressures until the unit can be repaired or replaced.  Dual-Window Sight Flow Indicators and Factory Mutual System Approved Dual-Window Sight Flow Indicators are available in 150# NPT Models and 150# and 300# Flanged Models.  FM-Approved 150# units are rated for 150 psig.  FM-Approved 300# units are rated for 300 psig.

Dual windows are comprised of two glass discs held in position by a metallic housing, internal shims and gaskets (pictured above).

The double, tempered glass window design provides added protection in applications where there is:
External mechanical impact - if the outer glass is cracked or shattered, the inner glass can temporarily continue in service until the unit can be repaired or replaced.
Abnormal compressive forces - in maintenance or replacement situations, the housing assists in alignment of the glass and can absorb uneven or excessive compression.
Thermal shock - in high temperature applications the inner and outer glass protect one another from an extreme thermal gradient.  The air pocket between the glass provides an insulative effect.
Corrosion/erosion - if the inner glass is weakened and it breaks, the outer glass can temporarily contain the fluid, withstand the pressure, and continue in service until the unit can be repaired or replaced.
