PTFE Lined Sight Flow Indicators

Product Description :

PTFE Lined Sight Flow Indicators  are commonly used in pipelines across industries to observe flow. While the traditional Sight Flow indicators work in most industries, in certain applications the metal bodies do not work, due to chemical incompatibility with the process media. For such applications,

Noble offers the complete range of Sight Flow Indicators with PTFE lining which comes in contact with the process media.

Noble offers both tubular as well as double window Sight Flow Indicators with FEP and PFA lining. The body of the Flow Indicator is usually made of Cast Ductile Iron or various stainless-steel grades. The wetted parts are completely lined with polymers such as FEP or PFA, ensuring complete corrosion resistance.

PTFE Lined Sight Flow Indicators are hence used for flow monitoring in corrosive environment like transfer of acid, alkalis and other corrosive chemicals in chemical process plants, food processing plants, petrochemical plants and in various other industries such as pesticides, fertilizer, dyes, paper and pulp processing plants.
