Inline Flow Sight Glass for Reliable Process Monitoring
The Inline Flow Sight Glass is a visual flow monitoring device designed for installation directly into industrial pipeline systems. It provides operators with a clear view of liquids, gases, slurries, and process media flowing through the line, helping verify flow conditions and detect operational abnormalities in real time.
The transparent viewing chamber allows quick inspection of flow rate behavior, fluid color, contamination, bubbles, foam formation, sediment buildup, and product consistency without interrupting production.
Constructed from high-quality stainless steel and equipped with precision-machined sealing surfaces, the sight glass offers excellent corrosion resistance, mechanical strength, and long-term reliability in demanding industrial environments.
Viewing sections are available with borosilicate glass, tempered safety glass, fused quartz glass, or other specialized transparent materials depending on temperature, pressure, and chemical compatibility requirements.
The Inline Flow Sight Glass is widely used in chemical processing, pharmaceutical manufacturing, food and beverage production, petrochemical plants, water treatment facilities, and industrial utility systems where visual confirmation of flow is essential.
Inline Flow Sight Glass— Technical Data
| Item | Details |
|---|---|
| Applications | Inline Flow Sight Glass has a plain straight through borosilicate glass tube with stainless steel flanged ends and is used to check for the presence of a liquid where there is intermittent flow, partially filled lines or entrained air. It can be used in vertical or horizontal lines & is ideal for you to visually check the presence, colour and condition of a liquid. |
| Construction | – Standard Flanges include ANSI 150 & PN16 – Flanges in 316 stainless steel – Stainless steel tie rods & fasteners hold flanges in place for a rigid construction – Borosilicate glass – Viton O-Ring or PFA (Teflon) encapsulated Viton seals offer superior protection – Outer O-Ring spacers ensure accurate glass alignment |
| Quality | – Manufactured to the highest standard – Quality system is independently certified to ISO9001. – Indicators are fully PED compliant & CE marked where required – Full material traceability is maintained, material Test certificates & pressure test certificates supplied on request |
