Title: Innovations by Yi Liu: Pioneering Flow Measurement Technologies

Introduction

Yi Liu is an accomplished inventor based in Bolton, MA, with a remarkable portfolio of six patents. His work primarily focuses on advanced flow measurement systems, showcasing his expertise in the field of ultrasonic technology.

Latest Patents

One of Yi Liu's latest innovations is the Anti-parallel tag flow measurement system. This system features a unique design where two measurement paths are established across a flowing fluid. Each path includes a receiver that captures signals modulated by scatters within the fluid. Notably, the direction of signal propagation in one path is anti-parallel to that in the other, allowing for enhanced correlation of receiver outputs to determine flow velocity. This innovative approach enables effective operation in challenging measurement scenarios, such as small conduits and low flow rates.

Another significant patent is the Layered ultrasonic coupler. This assembly consists of a barrier layer that contacts the wall, complemented by a thicker compliant material layer, such as zinc foil. The design ensures that the compliant layer does not directly contact the wall, preventing installation errors. This technology is particularly beneficial for cryogenic applications, where materials like indium can be utilized without the risk of alloying or migration.
