Flow indicators

The task of a flow indicator or an inspection glass of the piping is to show visually whether the medium is running in the pipeline or not. In order to make the observation easier, rotating rotors can be added to the flow indicator being operated with liquids.

Installation on the pressure side

When using the unit in a steam pipe to disclose a possible water load of the system, the indicator should be installed before the steam trap. In this case the flow indicator is able to detect a possible leakage in the steam trap.
