Sight flow indicators are engineered to provide maximum visual observation of liquid and gas flows through pipelines.
All glass windows are made of borosilicate glass and can be furnished with special Mica liners to protect against erosion and corrosion. Bodies are manufactured from durable ductile iron and range in sizes from 3/8" to 4" with threaded and flanged options.
