SPECTEC sight flow indicators provides a quick, reliable and economical way to verify fluid flows through industrial process lines. Sight flow indicator is available with four styles of indicators including rotor wheel, flapper, or drip tube, plain. A rotor wheel indicator style is ideal for indicating flow of clear or opaque liquids as well as observations from a distance. It can be installed in any direction, upward, downward, vertical or horizontal lines.
A flap indicates at a glance which direction the flow is moving in horizontal lines or vertical lines with upward flow. A port in the shape of a whistle or drip tube is ideal for gravity flow, extremely low flow or intermittent flow. The drip tube keeps the fluid from dripping on the sight glass, ensuring visibility.
