“…Wang et al proposed a differential pressure type FBG flowmeter, in which two FBG are pasted on the diaphragm to obtain the flow rate. However, the problem of temperature and strain cross-sensitivity is not solved in practical application, and the accuracy is low in complex environment [6] . Liu et al proposed a cantilever flow meter based on FBG.…”

This paper designs and makes a high precision and miniature fiber Bragg grating (FBG) gas flow sensor for the low measurement accuracy and large volume of traditional electromagnetic flow sensor in complex working environment. The flow sensor is selected, and the high ratio diameter nozzle is used as the throttle element to produce the pressure difference on both sides of the nozzle. By pasting the FBG along the radial direction on the sensitive diaphragm, the deformation caused by the induction diaphragm due to the pressure difference, so as to associate the flow change with the FBG wavelength drift. The mathematical relationship between the measured gas flow and FBG wavelength values is derived from theoretical and simulation, and the dynamic flow characteristics of the flow sensor are obtained through experimental calibration. The experimental results show that the flow change and FBG wavelength drift, consistent with the theoretical analysis, the flow sensor dynamic flow measurement sensitivity is 11.04 NL/min. The FBG gas flow sensor designed in this paper has the advantages of high precision, miniaturization, strong anti-electromagnetic interference ability and easy integration in the complex working environment.

“…In 2017, Yang Zhang et al proposed a lowpower-consumption, all-fiber-optic anemometer based on a tilted fiber Bragg grating that was coated with single-walled carbon nanotubes [13]. More recently, a hot-wire flowmeter, using a fiber extrinsic Fabry-Pérot interferometer combined with a FBG, was reported by Tianxi Zhang et al [14].…”

An all-fiber distributed airflow sensing method based on a differential pulse-width pair Brillouin optical time domain analysis (DPP-BOTDA) and a self-heated high-attenuation fiber (HAF) is proposed and demonstrated. The HAF heated the sensing fiber, producing a gradient temperature distribution in it through physical contact, where the temperature distribution was obtained by DPP-BOTDA with a spatial resolution of 5 cm. The heat loss caused by the airflow was reflected in the decrease in the Brillouin frequency shift and spatially resolved by DPP-BOTDA. Distributed airflow sensing was experimentally demonstrated for measurements of airflow movement, multiple airflow sources and the deflection angle of the airflow. The positioning error of the airflow was no larger than ~2.2 cm; for the deflection angle measurements of the airflow, the maximum demodulation error was 2.5° within the angle range of 0–30°.
