Title:

Tilt Sensor for Acoustic Doppler Velocimeter with Remote Head

Measuring and cataloging flow velocities in different bodies of water all over the world is an essential part of marine studies. Understanding water dynamics, or how water moves throughout an environment is very important for modeling physical processes like sediment transport and thermal stratification. Flow velocity plays a crucial role in determining ecosystem safety and health. Many organisms rely on specific flow conditions for spawning, feeding, or migration. In addition, the flow velocity of water through an ecosystem heavily influences distribution of nutrients, oxygen, and pollutants, directly affecting ecosystem health. Perhaps most importantly, measuring flow velocities in rivers is crucial for predicting flood risks during heavy rainfall or snowmelt. The collection of flow velocity data helps in designing early warning systems and building flood prevention structures like levees and dams. Whether it is a river or an ocean, water flows in every direction. Some directions much stronger than others, but each direction is important. The Nortec Vector probe detects flow velocities in the X, Y & Z directions simultaneously. But if it is not perfectly level, then the flow velocities in each direction will be calculated incorrectly thus skewing the data. The purpose of my project was to manufacture a device that could be mounted on the three-pronged head of the vector probe and display its orientation to ensure accurate data collection.
