Sight flow indicators by GMI.

Sight flow indicators

The purpose of the GMI sight flow indicator is to indicate the flow of a fluid in a pipe or tank. A visual determination of fluid flow is made either by transparency for coloured liquids or via a mechanical indicator such as a ball, a vane, etc.
