The extremely compact Flotect® V6 flow switch is designed to
monitor the flow rate of liquids, gases or air. It operates
magnetically and has no mechanical connections for easy and
reliable operation.
The lower body has vanes and a magnet that operates the switch by
controlling the magnet in the upper compartment. In most
applications the switch is normally open and the fluid in the pipe
makes the vane
The leaf spring is compressed, and when the flow rate decreases,
the spring pushes the leaf back into place, triggering the switch
to alarm or close. Optional tee to easily install the flow switch,
the tee is safe
Fitted pipe sizes are 1/2" - 2", and when sleeved, are well suited
for 1/4" and 3/8" pipe.
