The sight flow indicator is used for locally checking the liquid flow passing in pipe lines. It includes a double glass construction with either toughened or borosilicate glass depending on operating temperature. The glass has a look through design. Our sight flow indicator is made from bar stock material and is therefore available in all machinable materials.
