Abstract

The invention discloses an optical fiber laser flow meter which comprises an outer shell (10), a fixing beam (50) and an optical fiber laser device (30), wherein the outer shell (10) is used for fixedly connecting an optical fiber laser flow meter with a measured pipeline; the fixing beam (50) is mounted in the outer shell (10); and the optical fiber laser device (30) is mounted on the fixing beam (50) and is used for measuring the fluid flow. The optical fiber laser flow meter is utilized to solve the technical problems that the present flow meter influences the flow and the flow field of an original pipeline and to simplify the structure of the flow meter.

Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to an optical fiber laser flowmeter, which is suitable for measuring the flow of fluid. Background technique [0002] In many fields of industrial production and people's life, it is necessary to monitor the flow of fluid. Currently, commonly used flowmeters include target flowmeters, turbine flowmeters, and vortex flowmeters. Most of these flowmeters measure the force, speed or vibration signal through the electric sensor, and then input it into the analysis equipment for calculation, and finally get the flow value. However, electronic sensors have problems such as poor sealing, easy leakage, easy corrosion, and electromagnetic interference. [0003] Optical fiber sensors use optical fibers for sensing and transmission, and do not have the above-mentioned problems, so they have received more and more attention in recent years. However, there are still many problems in t...
