880 series flanged sight flow indicators

880 Series are a range of industrial double window sight glasses with either DIN or ANSI flanged connections up to 10” (DN250) in size. Available in Cast Iron, Carbon Steel or Stainless Steel and a choice of soda lime or Borosilicate glass there are options to suit most process industry needs. They come with a choice of a plain drip tube which is ideal when you need to inspect for bubbles, colour or quality of the media, if rudimentary indication of flow is required a flap or spinner can be provided. Primarily designed for low viscosity liquids or gases (drip tube and flap only, not spinner type), they can be mounted horizontally or vertically.
