Raven Filter Media Manager, Square Rail Clamp, 25' Cable

Description

The Raven Filter Media Manager quickly and accurately measures media expansion during backwash. Achieving proper media filter bed expansion during backwash in gravity filters is a crucial step in maintaining filter performance and longevity. The US EPA recommends 20% to 25% filter bed expansion to adequately clean the filter media (anthracite, sand). Failure to expand the bed sufficiently will result in "mud balls" that degrade the filter's ability to trap dangerous microorganisms such as Cryptosporidium oocysts and Gyardia cysts. How it works: Lower the sensor to rest on the compacted media bed prior to backwash. Press "Zero" on the controller to set the counter to zero. As the dirt and debris is being evacuated, the red light will illuminate. When the backflow water becomes clear, the media will begin to rise with expansion. Raise the sensor slowly until the red light goes out. Repeat until the bed finishes expanding. The amount of expansion will be noted on the display. Made in USA. Note: the Filter Media Manager will ship in two containers.
