Title: Subrahmanyam Surya Venkata Sista: Innovator in Viscosity Measurement Technologies

Introduction

Subrahmanyam Surya Venkata Sista is a notable inventor based in Hyderabad, Telangana, India. He has made significant contributions to the field of viscosity measurement, holding a total of 4 patents. His work focuses on developing advanced technologies that enhance the accuracy and efficiency of viscosity measurements in various applications.

Latest Patents

One of his latest patents is for an active sensor for torque measurement in a viscometer. This invention allows for the determination of the viscosity of a sample fluid at a surface location under various downhole conditions prior to the fluid being pumped or flowed downhole. The viscosity assembly includes a bob assembly within a container, featuring a bob that rotates around a magnet rotor when a shear force is applied by the fluid flow. A stator coil receives a control signal that induces a force or voltage, causing the magnet rotor to rotate the bob back to its initial position after a predetermined distance.

Another significant patent is for a multi-surface viscosity measurement system. This system comprises a rotor cup with an inner chamber, where a first bob is rotatably disposed within a first region, and a second bob is rotatably disposed within a second region. The second bob rotates relative to the first bob based on the difference in viscosity of the fluid in the two regions, allowing for precise viscosity measurements.
