Abstract/Summary
Data acquisition is an essential part of the research and development process of water valves and fittings at Zurn Wilkins. In Fall 2021, Zurn Wilkins approached our senior project team with a goal of creating a modular data acquisition system that streamlines their design and testing processes for new products. Our team determined that a microcontroller-based system was the optimal way to deliver this goal and designed our system around a Raspberry Pi. We chose twelve sensors that were compatible with existing taps in the Zurn Wilkins facility. The sensors send their signal through waterproof receptacles into the Polycase waterproof enclosure to the Analog Digital Converters (ADCs). The ADCs convert a 4-20mA signal from each of the sensors into digital data that can be processed by the Raspberry Pi. We used DIN rails and compatible mounting kits to mount these components into our enclosure. The system accepts user input through the LCD screen with buttons and displays values during setup and data collection. The system was assembled and calibrated by the team, resulting in the ability to accurately read pressure, temperature, and flowrate data from a fluid system. The testing of our project proved that we met or exceeded each of the specifications set forth at the beginning of the project. We have delivered our fully operational system to our sponsor contact, who will use it to expedite his data collection process in his everyday life as a water solutions engineer.
