Sight Flow Indicators

Kadant sight flow indicators are engineered to provide visual observation of liquid and gas flows. These pipeline indicators are available with ductile iron or bronze bodies. All glass windows are made of Pyrex® or equal. Indicators can be furnished with special transparent-type Mica liners to protect glass against erosion and corrosion. Sight flow indicators are available in sizes from 3/8" to 4" with threaded and flanged options.
