Parker/Page’s new sight flow indicators are designed to allow the flow monitoring of ultrapure liquids and harsh chemicals. The units can be used in vertical or horizontal lines to visually inspect for contaminants, flow interruptions and leak detection. Manufactured from chemically inert fluoropolymer tubing capable of withstanding corrosive applications and high temperatures, the low refractive index polymers offer high visibility and a superior strength-to-weight ratio. They can be manufactured in FEP or PFA with a variety of flow ranges and fittings. Sanitary, flange, instrumentation, butt weld or fluoro-polymer-lined fittings are the most common, but other fittings are available upon request. The indicators are available in sizes from one-half to four inches (12.7-101.6 mm). http://[email protected]
