The FL-500UP is a specialized
meter for monitoring the flow rate
of ultra-pure water to tools, on
de-ionized water returns, and UPW
returns. Also available are
accessory switches for signaling
specific flowrates. Each switch kit
contains all the necessary hardware
for quick and trouble-free mounting.
Kits include a ring-shaped PTFE­coated 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. An
adjustment screw allows for easy
flow rate adjustment. Add 2 switches
to indicate both high and low flow
rate limits.

Note: Switch activates over a 25% FS
band; above and below this band, the
relay deactivates.

Polysulfone should not be used in

direct sunlight or any other significant

sources of ultraviolet light.
