Vortex street flowmeter identification and processing the noise of the scale

Abstract: the scale vortex flowmeter noise identification and processing of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Interference field application of vortex flowmeter has universality, complexity and randomness, space electromagnetic interference source, liquid flow, pipe installation and environmental vibration caused by interference, upstream choke flow field interference, etc. , are in different liquid. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a vortex flow meter scale noise identification and treatment of the article details. Interference field application of vortex flowmeter has universality, complexity and randomness, space electromagnetic interference source, liquid flow, pipe installation and environmental vibration caused by interference, upstream choke flow field interference, etc. , are realized in different ways to affect the normal work of the vortex flowmeter. The technology of small make up remind everybody here, flowmeter, in every link of vortex street flowmeter, should take measure to restrain the interference and noise intrusion and influence. Vortex street flowmeter microprocessor was applied, the instrument flow characteristic, fluid state parameter modification and compensation, improving the measuring precision of instrument, and give all sorts of intelligent functions. Another important aspect is to develop the function of it in signal processing, to identify with the signal and noise, the true, combine the above two aspects is very good, the performance of the instrument can really improve. The study of vortex flowmeter signal and noise, the researchers at home and abroad have done a lot of work, basically has the following several aspects. 1. Starting from the study of the stability of the karman vortex street, the geometric parameters of body experiment research, choose the vortex signal is strong, stability good body, improve the signal-to-noise ratio of the vortex street. 2. From the study of detection method of vortex signal, choose the strong signal, noise detecting element and the installation position of detecting element, using differential detecting element to remove the influence of noise and interference. 3. Study of vortex street characteristics and differences between signal and noise, was carried out on the vortex signal and noise filtering. 4. Application of digital technology on the frequency spectrum of the signal and noise analysis and process, to eliminate the influence of noise. The above four steps, the first two belong to the conventional method, after two in the fast breakthrough and progress in recent years. Especially after traditional instrument combined with microprocessor, application of digital signal processing technology of the instrument, significantly enhance the instrument performance. If you have other problem about flow meter, flow meter manufacturer, we will serve you wholeheartedly. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
