The TK3W Series stainless steel paddle wheel flow meter has been designed for tough industrial applications. The TK3W series paddle wheel flow meter has been engineered to provide long-term accurate flow measurement of liquids. The 316SS in-line flow meter is a blind unit equipped with an LED flow indicator and can provide pulse, 4-20mA or voltage outputs. 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.
