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.
