Model / series: PFT
The PFT is an insertion paddlewheel flow sensor for water and water-based fluids. One size-adjustable sensor fits pipes from 1-1/2 to 40 inches, and hot-tap versions can be fitted without shutting the line down. Its non-magnetic sensing and PTFE bearing give a long life even with some particles in the water.
