ASME B16.5 Class 300 Flow Indicator, Carbon Steel, with Rotator, Size 3

Rotator style flow indicator with ASME B16.5 Class 300 flanged connections, in carbon steel housing. Designed with front and back windows for backlighting making it easy to see flow variations inside any pipeline, even when used with dark liquids. There is a rotating wheel between the two windows enabling to quickly see if there is any flow going through the pipe. This flow indicator is installed in-line of the pipe between two mating ANSI RF flanges, in any position to indicate flow in any direction. The visibility of the rotor motion makes this style particularly well suited for monitoring clear, translucent or solutions with dark colors, as the rotator is clearly distinguished from the background of the fluid.Tempered borosilicate glass windows are internally sealed to the metal housing with Neoprene flat gaskets. Standard safety and maintenance features include: Independently bolted glass retainers; Acrylic enamel coating surface finish.
