TKP In-Line Paddle Wheel Flow Meter

Brand: Truflo®

The TKP Series digital paddle wheel flow meter has been designed for tough industrial applications.

The TKP series paddle wheel flow meter has been engineered to provide long-term accurate flow measurement for both corrosive and non-corrosive liquids.

The plastic in-line flow meter is equipped with a 360° rotatable vivid LED display showing both Flow Rate & Flow Total and provides a frequency pulse output.

The re-engineered low-drag, fluid-dynamic design of the paddle wheel allows it to stand alone as the industry’s most accurate flow meter.

Icon’s digital paddle wheel flow sensors incorporate a Tefzel® paddle coupled with a zirconium ceramic rotor pin and bushings.

The TKP series liquid flow sensor, is industry’s longest lasting paddle wheel flow sensor and comes with a lifetime warranty on the paddle wheel assembly.

The TKP in-line chemical flow meter incorporates a true-union design with body materials available in PVC, PP and PVDF.
