 The Blancett Model 1200 In-Line Turbine Flow Meter was engineered for applications in high corrosive environments. Developed for use in petrochemical and other process industries with liquid chemical flows, the Model 1200 Turbine provides accuracy and durability in aggressive industrial environments. The meter features a 303 stainless steel body and internal wetted parts, with two Type 440 stainless steel ball bearings.
Fluid entering the meter passes through an inlet flow straightener and a hydrodynamically shaped deflector cone to reduce its turbulent flow pattern. Fluid then passes through the turbine, causing the turbine to rotate at a speed proportional to fluid velocity. The rotating turbine blades modulate a high frequency carrier wave in the externally-mounted RF pick-up.
