Sight Flow Indicators

Search within this category

Gain an inside view of gas and water pipelines with sight flow indicators. Crystal-clear tubes and windows made from tempered glass or durable plastic make it easy to visually monitor flow-through from just about any angle, while built-in flapper, rotary and other types of indicators help you monitor flow rate at the same time.
