Sight Glasses

At BM Engineering, we supply a wide range of sight glasses from equipment specialists Inoxpa and Valsteam ADCA. We offer many different types of sight glasses including tubular, clamp and flat. Sight glasses come in three different styles:

  • Tubular sight glass – This is where the sight glass acts as a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
  • Circular sight glass – A circular pane of glass through which an operator can view inside a vessel.
  • Sight flow – An in-line style sight glass which allows the flow of a fluid in a pipeline to be observed.
