3D printed Coriolis mass flow sensor

Research output: Working paper


This paper presents the first 3D printed Coriolis mass flow sensor that has been tested using water flow from 0 to 150 g/h. The sensor consists of a free-standing tube printed by an LCD 3D printing technique. The outer tube surface is metalized by copper plating to allow for the actuation of the tube by Lorenz forces. The displacement of the tube is detected by a laser doppler vibrometer (LDV). The tube has a circular cross-section with an inner diameter and wall thickness of approximately 900 μm and 230 μm, respectively. The relatively large diameter results in a low-pressure drop of 30 mbar at water flow of 150 g/h.
