The FL-500-RI proximity switches generate electrical signals at
your predetermined flow rates, adding versatility and performance
to the FL-500 Series flowmeters. Each switch kit contains all the
necessary hardware for quick and trouble-free mounting. Kits consist
of a ring-shaped ceramic magnet that fits around the float in the
flowmeter and a proximity switch mounted in a rugged housing that
easily clamps to the body of the flowmeter. As the changing flow
causes the float to move within the tube, the magnet moves with it,
and its magnetic field trips the proximity switch at the predetermined
flow rate. Adjustment screw allows for easy flow rate adjustment. Add
two switches to indicate both high and low flow rate limits.
