      A sight glass flow indicator from Grainger can indicate liquid level in a tank or help you see the presence or clarity of fluids in a piping system. The 360° clear viewing area can resist clouding, cracking and discoloration, and the flow indicator's round design helps deter collection of debris in corners. Single wall models feature acrylic sight material that helps prevent breakage on impact. Double-wall and wafer style models feature Pyrex inner walls to help resist corrosion. Choose the style and size that fits your application. Shop Grainger today for a high-quality sight glass flow indicator.
