Title: Innovations of Andrew K. Levien

Introduction

Andrew K. Levien is a notable inventor based in Menlo Park, CA. He has made significant contributions to the field of flow measurement technology. With a total of 3 patents to his name, Levien's work focuses on advanced sensor apparatuses that enhance the accuracy and efficiency of mass flow rate measurement systems.

Latest Patents

One of Levien's latest patents is a sensor apparatus for a mass flow rate measurement system. This invention features a dual-tube Coriolis flow meter, where each tube is formed into a loop. The loops are connected in either series or parallel flow relationships, allowing them to accept portions of the flow in a flow line. The design includes small permanent magnets attached to each loop, which interact with a drive means to impart oppositely directed drive forces. Sensors positioned at the extremities of the loops induce signals proportional to the relative motions of the loop ends.

Another significant patent is the single tube parallel flow Coriolis mass flow sensor. This device consists of a single continuous tube folded in a helically looped fashion. The straight input and output segments of the loop are positioned in parallel, allowing fluid to flow in the same direction in both segments. An oscillatory drive mechanism is coupled between the straight segments, enhancing the sensor's functionality.
