Model 1198 is available with three styles of indicators including paddle wheel, flap style or drip tube/whistle shape. Many specials are also available upon request to meet various conditions of pressure, temperature, fluid types and mechanical dimensions.
1198M type: A paddle wheel indicator style is ideal for ndicating 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.
1198C type: A flap indicates at a glance which direction the flow is moving in horizontal lines or vertical lines with upward flow.
1198S type: 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.
