KSR/SVN - Low Volume Flow Switch for Liquids or Gases

KOBOLD micro flow switches, models KSR and SVN, operate on the same principle as a float-type or variable area flow indicator.

Provided that the flow rate is above a preselected minimum, the float is raised from its seat and travels the full distance to its upper stop.

The SVN utilizes an inductive proximity switch which transmits a signal to a suitable power supply/relay module, such as our KFA or KFD series, triggering a user specified signaling or switching sequence.

The KSR contains a magnet within its float, which activates an electrically isolated reed-switch.

As long as the maximum switching capacity of the reed switch is not exceeded, no supplemental relay is required to provide a triggering function.

If additional switching capacity is required, KOBOLD can supply an appropriate isolation relay to protect the flow switch contacts from overload damage.
