A modal interferometer based system to improve performance of vortex flowmeter and a method thereof

    Abstract:

Applications: The present invention discloses a fiber optic based sensing system for embedding in a vortex flowmeter for detection of vortex shedding frequency at low flow rates and high temperature. The developed fiber optic based sensing system comprises a highly sensitive optical fiber modal interferometry based sensor which can detect the vortex shedding frequency at low flow rates and improves the overall operating range of the flowmeter. The optical fiber modal interferometry based sensor involves periodic arrangement of silica and air holes for operating as the interferometer and generating temperature fluctuations independent interference pattern sensitive to incident frequency and hence vortex flow enabling said vortex flowmeter to accurately measure fluid flow rates at high temperatures and or low flow rates irrespective of external vibrations.
Advantages: Online monitoring, can work for very low flow rates

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
