Flow indicators
The propeller flow indicators are designed to visually signal the passage of a fluid in a tube. They are normally used in lubrication, refrigeration, heating, and water treatment plants in the chemical, food, and pharmaceutical industries. These visual level indicators can be installed both vertically and horizontally to control non-viscous transparent liquids, free of impurities.
The tubular visor of the flow indicator, made of glass, is also suitable for use with solutions containing glycol and guarantees maximum visibility of the flow from every angle. The end flanges, the axis, and the helical rotor are made of technopolymer. Upon request, stainless steel (AISI 316) bushings, bushings with NPT conical gas threads, axle, and propeller rotor in blue color are also available.
