The FL-500UP is a specialized meter for monitoring the flow rate of ultra-pure water to tools, on deionized 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.
