The PTFE Lined Sight Flow Indicator is a robust and corrosion-resistant device designed to provide visual observation of fluid flow in pipelines carrying highly aggressive or hazardous chemicals. It features a chemically inert PTFE lining that ensures maximum resistance to corrosion, along with a high-visibility glass viewing window for safe and effective monitoring of process fluids. Ideal for use in industries such as chemical processing, pharmaceuticals, petrochemicals, and wastewater treatment, this flow indicator combines the strength of a metallic body with the superior chemical resistance of PTFE.
Applications:
Corrosive Liquid Flow Monitoring
Acid and Chemical Transfer Lines
Water and Effluent Treatment Plants
Pharmaceutical and Bio-Process Plants
Solvent Flow Observation
Agrochemical and Dyes Industries
