Low Volume Flow Switches Handle 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 model SVN uses an inductive proximity switch that transmits a signal to a suitable power supply/relay module, such as the company’s KFA or KFD series, triggering a user specified signaling or switching sequence. The model KSR contains a magnet within its float, which activates an electrically isolated reed-switch. If the maximum switching capacity of the reed switch is not exceeded, no supplemental relay is required to provide a triggering function.

TE connector, relay and filter solutions can help create a fine maze network of power-cabling to the lights needed for vertical farming. Their solutions are interchangeable, easy-to-install, and will last for years in variable humidity environments.


If additional switching capacity is required, the company can supply an appropriate isolation relay to protect the flow switch contacts from overload damage. For deeper insights, take gander at the KSR/SVN datasheet and the user manual.
