This semester I am a member of the Linear Chemical Dose Controller (LCDC) team. As part of the Fall 2012 LCDC team, our challenge included creating and refining a prototype of the lever arm assembly. Refer to the Chemical Dose Controller page for a copy of the team tasks, final report, presentation, and videos of the LCDC system in useand presentation.
After creating a prototype of the lever arm assembly and LCDC setup, as a team we made modifications to the existing design which included: a new drop tube connection designed to reduce leakage, adding cross bracing to the lever arm assembly to reduce bending of the lever arms, adding a calibration device to enable fine-tuned adjustments, and testing the linearity of the new lever arm assembly. Finally, in order to create an aesthetically pleasing design we modified the weight design, had the lever arm assembly anodized, and had a label, scale, and logo mechanically engraved on the lever arm.
