Real-time embedded pressure and flow rate sensor in
This paper presents an embedded and miniaturized pressure sensor based on the Fiber Bragg Grating (FBG) technique for the measurement of both flow rate and flow-induced pressure in
Analysis of fluid flow in a cylindrical tube using fiber Bragg grating
In this study, FBG is used to monitor the fluid flow rate in a pipe by analyzing changes in the output power generated by the FBG. This research was designed by varying the pipe diameter,
Fiber Bragg Grating Target Flow Sensor Based on Fixed Beam and
A novel fiber Bragg grating (FBG) flow sensor with high sensitivity is proposed in this article, which consists of a target disk, a solid beam, an L-shaped leve
Fiber Bragg Grating
Fiber Bragg Grating''s Side Mode Suppression Ratio (Sidelobe Suppression Rate or SLSR), is it better to have a larger or smaller SLSR? The Side Mode Suppression Ratio (SLSR) of FBG is a measure of
Design of Flow Velocity and Direction Monitoring Sensor Based on
At present, FBG sensors have been widely accepted in China, and the project client has designated the use of FBG sensors. Therefore, an FBG sensor for flow velocity and flow direction monitoring is
Fiber Bragg grating accelerometer-based nonintrusive flow rate
The flow rate is known to be related to the vibration excited by the turbulent internal flow, but there exists some scatter in the vibration data at low flow speeds (<2m/s) due to the resolution
Fiber Bragg grating sensor for simultaneous measurement of flow rate
A new fiber-optic sensor system consisting of a fiber Bragg grating cantilever as a transducer is proposed and demonstrated to realize simultaneous measurement of fluid flow rate and
Method for simultaneous measurement of velocity and direction of fluid
Thus, knowing the curves for different flow rates and analyzing the spectral characteristics of the entire FBG array, it is possible to determine not only the flow rate, but also its direction both
