TK3M – Stainless paddle wheel flowmeters with display
The TK3M Series stainless steel digital paddle wheel flow meter sensor has been designed for tough industrial applications. The TK3M series paddle wheel flow meter sensor has been engineered to provide long-term accurate flow measurement of liquids.
The 316SS in-line flow meter sensor is equipped with a 360° rotatable vivid LED display showing both Flow Rate & Flow Total and provides a 4-20mA 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.
