Sight Glasses

Sight Glasses, or Visual Flow Indicators, visual flow indicators show whether or not a fluid is flowing in a pipeline.
We manufacture flow indicators for both horizontal and vertical mounting, suitable for the most diverse industrial applications.

In order to improve the flow visibility, to the free passage version (SLE) the following indicators can be added:
  • Paddle: fixed (SBE) or moveable (SPO, SPA, SPD)
  • Chain (SCE)
  • Spheres in plastic material
  • Rotor
  • Drop indicator for vapours
On request they can be supplied with Thermo-well or in compact version.
