The Caleffi 626600A paddle flow switch is a durable, high quality water flow switch for pipe sizes from 1 to 8 inches. The heavy-duty line-voltage rated contacts can start equipment when flow is present (using the normally open contact) or lock out equipment when flow is present (using the normally closed contact). Trim the stainless steel paddle to length and mount the 626600A in a 1 inch female NPT connection. The IP54 (NEMA type 5) rated housing offers protection from damp and dusty environments and a handy 1/2 inch female NPT threaded conduit connection makes installation quick and professional.
Be sure to check the minimum (for example: 5.7 GPM in a 1 inch pipe) and maximum flow ratings - shown in the Technical Brochure - to make sure it's the right switch for your application. Bob "Hot Rod" Rohr explains more in the video below.
