Sight Flow IndicatorsSight Flow indicators allow the flow monitoring of ultra pure liquids and harsh chemicals and can be used in vertical or horizontal lines to visually inspect for contaminants, flow interruptions and leak detection. Made from chemically inert fluoropolymer tubing, the indicators withstand corrosive applications and high temperatures. Low refractive index polymers offer high visibility as well as superior strength to weight ratio, creating a virtually unbreakable site glass. Indicators can be manufactured in FEP or PFA with a variety of flow ranges and fittings. Sanitary, fange, instrumentation, butt weld or fluoropolymer-lined fittings are available, with other fittings available upon request. Sizes range from ½-4 in.
