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 utilizes an inductive proximity switch which transmits a signal to a suitable power supply/relay module, such as our KFA- or KFDseries, triggering a user specified signaling or switching sequence. The model 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, can supply an appropriate isolation relay to protect the flow switch contacts from overload damage.
