There is a rotating wheel between the two windows enabling to quickly see if there is any flow going through the pipe. 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.This flow indicator is installed in-line of the pipeline between two threaded pipe ends.
