The Truflo® TKM | TK3M Series In-Line Paddle Wheel Flow Meter Sensors are precisely engineered for exceptional performance in tough industrial environments. These sensors offer an innovative ShearPro® Paddle Wheel design, which reduces drag by 78% compared to traditional flat paddle designs, resulting in significantly increased longevity and efficiency.
The advanced materials used, such as Tefzel® for the paddle wheel and zirconium ceramic for the rotor and bushings, provide superior chemical resistance and wear resistance. This makes the TKM Series ideal for handling a wide range of chemical liquids while maintaining high accuracy and repeatability.
These flow meters come equipped with a bright LED display that can rotate 360 degrees, providing clear visibility and ease of reading from any angle. With options for various outputs including pulse, 4-20mA, and voltage outputs, these devices meet versatile industrial needs.
