Discrimination and Treatment of Noise of Vortex Flow Meter

Abstract: The identification and processing information of vortex flowmeter meter noise is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The interference of vortex flowmeter in field application is universal, complex and random. Electromagnetic interference in space, power supply interference, liquid flow interference, installation pipeline and environmental vibration interference, flow field interference caused by upstream blocking parts, etc. manifested in different ways. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the identification and treatment of vortex flowmeter meter noise. The interference of vortex flowmeter in field application is universal, complex and random. Electromagnetic interference in space, power supply interference, liquid flow interference, installation pipeline and environmental vibration interference, flow field interference caused by upstream blocking parts, etc. The normal operation of the vortex flowmeter is affected by different realization methods. Here, the technology of the flowmeter reminds everyone that measures to suppress interference and noise intrusion and influence should be taken in all aspects of the vortex flowmeter. The vortex flowmeter uses a microprocessor to correct and compensate the flow characteristics and fluid state parameters of the instrument, improve the measurement accuracy of the instrument, and endow the instrument with various intelligent functions. Another important aspect is that it can play its function in signal processing, identify and process the signal and noise, remove the false and preserve the true, and combine the above two aspects well, the performance of the instrument can be really improved. For the research on the signal and noise of vortex flowmeter, researchers at home and abroad have done a lot of work, mainly in the following aspects: 1. Starting from the research on the stability of the Kaman vortex street, experimental research on the geometric parameters of the generating body, Select the generator with strong vortex signal and good stability to improve the signal-to-noise ratio of the vortex. 2. Starting from the detection method of vortex signal, select the detection element with strong signal and low noise and the installation position of the detection element, and use the differential detection element to remove the influence of noise and interference. 3. Study the characteristics and differences between vortex signal and noise, and perform tracking filtering on vortex signal and noise. 4. Apply digital technology to analyze and process the spectrum of signal and noise to eliminate the influence of noise. Among the above four measures, the first two are conventional methods, and the latter two have achieved rapid breakthroughs and progress in recent years. Especially after the traditional instrument is combined with the microprocessor, the digital technology is used for the signal processing of the instrument, which greatly improves the performance of the instrument.
