HOME / Products / Flow Switches and Flow Controls / Sight flow indicators

Flow viewers in stainless steel, bronze, brass

Our sight flow indicators are ideal for instant checks to liquids in all industrial processes.

They are produced for instantaneous flow indication in horizontal pipelines either using a floating paddle with a scale that can be read on a backlit graduated double disc in toughened glass or using a pointer with a magnetic gear against a scale read on an external dial.
The sight flow indicators can be produced for a simple visual verification of the fluid without impeding the flow in any way.

Other possible specifications are production in other materials adapted to different fluids or threaded or flanged connectors.
