Research on monitoring method of flow field distribution based on multichannel ultrasonic flowmeter
Abstract
In order to solve the problem that it is difficult to monitor the flow field state in the pipeline during thecalibration process of the flowmeter, this paper proposes a method to monitor the symmetrical state of theflow field in the pipeline by using the cross four-channel flowmeter with different sound channel velocity. The signal decomposition method based on singular value decomposition (SVD) is separate the noise signal from the single of channel measurement result, the velocity distribution curve of the medium in the pipeline is obtained by using 8 acoustic channel velocities lo quantitatively monitor the flow field distribution. in view of the above flow field monitoring methods, a real flow experimental platform based on water flow standard device and cross four channel flowmeter is built to verify the flow field symmetry state monitoring method in the water flow standard device pipeline, the experimental results show that the method can be used to monitor the symmetrical state of flow field in the pipe of water flow standard device.
