Industrial Flow Switch 1/2"

Used this flow switch to detect flow that a traditional mechanical flow switch with paddle was unable to detect reliably. The only challenge was during installation. I had to use a reducer to fit this 1/2-inch threaded flow switch into the 1-inch fitting that the old mechanical switch used. The threads on the new 1/2-inch flow switch are NOT tapered, whereas those on the 1-inch to 1/2-inch reducer were tapered. I had to re-tap the reducer to remove the taper and have the new 1/2-inch flow switch thread all the way in and seal. A nuisance that delayed installation as I had to find and purchase a 1/2" by 14 NPT tap, which was not cheap. Once the new flow switch is hooked up electrically, you can adjust the trigger point to the application. In doing this exercise, I realized just how variable the flow was from my supposed constant-flow recirculation pump. Nonetheless, using the new flow switch's LED scale, I was able to accurately tune the system to trigger upon flow detection and remain triggered during circulation pump operation. Overall, this 1/2" flow switch was cost-effective (it was offered a promotional price when I purchased it), appears appropriately sensitive, and will hopefully prove reliable. Based on early use to-date, I would recommend this flow switch. I will wait to see whether the unit is reliable before I give a full endorsement.
