A signal processing method for coriolis mass flowmeter 用于科里奧利質(zhì)量流量計(jì)的數(shù)字信號(hào)處理方法
For the dft - based coriolis mass flowmeter , the key problem that greatly influence its precision is how to realize the integral period signal samples 摘要對(duì)基于離散傅里葉變換( dft )信號(hào)處理方式的柯氏質(zhì)量流量計(jì)來(lái)說(shuō),影響其精度的關(guān)鍵問(wèn)題是如何實(shí)現(xiàn)信號(hào)的整周期采樣。
A comparison of corrosion resistance among some sensor material available in coriolis mass flowmeter is introduced . material compatibility to the corrosive fluids in petrochemical industries is discussed in most detail 對(duì)質(zhì)量流量計(jì)現(xiàn)有的一些傳感器材質(zhì)的耐腐蝕性能作一比較,較詳細(xì)地分析了質(zhì)量流量計(jì)用于石油及化學(xué)工業(yè)中腐蝕性介質(zhì)的材質(zhì)適用性。
The coriolis mass flowmeter ( cmf ) is widely used in industries , because it has many advantages - high measurement accuracy , being able to measure fluid mass flow directly and measure various parameters of fluid , etc . originally analog signal processing methods are used for cmf , but some companies and institutes devote themselves to digital signal processing methods because they have many advantages over analog methods 科里奧利質(zhì)量流量計(jì)由于其精度高、測(cè)量流體范圍廣、可做多參數(shù)測(cè)量等優(yōu)點(diǎn),在工業(yè)上獲得了廣泛的運(yùn)用。原來(lái)的科氏流量計(jì)的信號(hào)處理主要是采用模擬電路,由于模擬信號(hào)處理系統(tǒng)存在很多缺點(diǎn),越來(lái)越多的公司和研究機(jī)構(gòu)都投入大量的人力物力來(lái)研究數(shù)字信號(hào)處理方法和系統(tǒng)。
