橢圓齒輪流量計流量信號(即橢圓齒輪的旋轉(zhuǎn)速度n)的顯示，有就地顯示和遠(yuǎn)傳顯示兩種。就地顯示將齒輪的轉(zhuǎn)動通過一系列的減速及調(diào)整轉(zhuǎn)速比機(jī)構(gòu)之后，直接與儀表面板上的指示針相連，并經(jīng)過機(jī)械式計數(shù)器進(jìn)行總量的顯示。遠(yuǎn)傳顯示主要是通過減速后的齒輪帶動永久磁鐵旋轉(zhuǎn)，使得彈簧繼電器的觸點(diǎn)以與永久磁鐵相同的旋轉(zhuǎn)頻率同步地閉合或斷開，從而發(fā)出一個個電脈沖遠(yuǎn)傳給另一顯示儀表，陜西金屬管浮子流量計制造商.橢圓齒輪流量計計量精度高，適用于高粘度介質(zhì)流量的測量，但不適用于含有固體顆粒的流體，如果被測液體介質(zhì)中夾雜有氣體時，也會引起測量誤差。通常橢圓齒輪流量計的精度可達(dá)0.5級，陜西金屬管浮子流量計制造商，是一種較為準(zhǔn)確的流量計量儀表，但是，如果使用時被測介質(zhì)的流量過小，陜西金屬管浮子流量計制造商，橢圓齒輪流量計儀表的泄漏誤差的影響就會突出，不能再保證足夠的測量精度。測量蒸汽只能用專門設(shè)計的金屬管浮子流量計或在標(biāo)準(zhǔn)型儀表上加裝附加構(gòu)件。陜西金屬管浮子流量計制造商</p><div

實際上大部分浮子流量計同一儀表可用于液體也可用于氣體，結(jié)構(gòu)上是通用的。只是我國浮子流量計行業(yè)標(biāo)準(zhǔn)等規(guī)定流量上限Qmax必須符合（1，，，4或6）×10nL/h的要求（n為正負(fù)整數(shù)或零），為液體（以水為表示）設(shè)計的儀表用于氣體（以空氣為表示）時，不符合上述要求，只能為氣體另行設(shè)計浮子和錐管，就分成液體和氣體兩種系列。國外有些制造廠同一儀表并列液、氣兩種流體的流量范圍，當(dāng)然流量值就不可能都是圓整值；國內(nèi)有些型號儀表也采用本辦法。但是液體用和氣體用設(shè)計還是有區(qū)別的，例如氣體儀表浮子設(shè)計得較輕，防浮子振蕩跳動的阻尼件結(jié)構(gòu)各異等。測量蒸汽只能用專門設(shè)計的金屬管浮子流量計或在標(biāo)準(zhǔn)型儀表上加裝附加構(gòu)件，例如增加帶散熱片的液體阻尼件，以減少浮子跳動；與指示轉(zhuǎn)換部分連接處隔以散熱片。陜西金屬管浮子流量計制造商由于分流管中置有限流小孔板，起到補(bǔ)償主孔板流量和差壓間平方根非線性關(guān)系，流量示值基本是線性的。</p><div

低維護(hù)量-市場上大多數(shù)的渦街流量計是采用取壓孔或插入式檢測元件感應(yīng)漩渦，一旦介質(zhì)中雜質(zhì)嵌入取壓孔或感應(yīng)元件與表體間的縫隙，則造成信號變?nèi)趸虿环€(wěn)定。良好的設(shè)計應(yīng)該是沒有容易堵塞的部分，從而降低維護(hù)量。 </p> <p> 2. 感應(yīng)元件在線更換-某些廠家的感應(yīng)元件與渦街發(fā)生體合二為一，看似簡單的設(shè)計卻給實際使用帶來不便。因為一旦感應(yīng)部分失效，則需要將管道內(nèi)介質(zhì)排空泄壓后更換部件，影響生產(chǎn)。完善的設(shè)計應(yīng)該是將二者分開，這樣就可以單獨(dú)更換感應(yīng)部分，而無需將介質(zhì)排空。 </p> <p> 3. 渦街流量計容易受到振動的干擾，設(shè)計精良的渦街流量計可以通過硬件和數(shù)字信號處理將干擾排除，從而得到穩(wěn)定的信號。 </p> <p> 4. 渦街流量計安裝的一麻煩是前后需要很長的直管段，有些廠家可以提供在流量計內(nèi)部縮徑的設(shè)計，降低了用戶專門維渦街流量計配備直管段的需求。 </p><p> 方面的考慮因素如下： </p> <p> 1．儀表性能方面：精確度、重復(fù)性、線性度、范圍度、壓力損失、上下限流量、信號輸出特性、響應(yīng)時間等； </p> <p> 2．流體特性方面：流體壓力、溫度、密度、粘度、潤滑性、化學(xué)性質(zhì)、磨損、腐蝕、結(jié)垢、臟污、氣體壓縮系數(shù)、等熵指數(shù)、比熱容、電導(dǎo)率、聲速、混相流、脈動流等； </p> <p> 3．環(huán)境條件方面：環(huán)境溫度、濕度、安全性、電磁干擾等；浮子流量計 </p> <p> 4．經(jīng)濟(jì)因素方面：購置費(fèi)、安裝費(fèi)、維修費(fèi)、校驗費(fèi)、使用壽命、運(yùn)行費(fèi)（能耗）、備品備件等。 </p> <p> <br /> 分流型浮子流量計結(jié)構(gòu)上分為分離型和一體型兩種。</p><div

在飽和蒸汽測量中采用VA型壓電式渦街流量變送器，由于渦街流量計量程范圍寬，因此，在實際應(yīng)用中，一般插入式渦街流量計主要考慮測量飽和蒸汽的流量不得低于渦街流量計的下限，也就是說必須滿足流體流速不得低于5m/s。根據(jù)用汽量的大小選用不同口徑的渦街流量變送器，而不能以現(xiàn)有的工藝管道口徑來選擇變送器口徑。 </p> <p> （2）壓力補(bǔ)償壓力變送器的選擇 </p> <p> 由于飽和蒸汽管路長，壓力波動較大，必須采用壓力補(bǔ)償，考慮到壓力、溫度及密度的對應(yīng)關(guān)系，測量中只采用壓力補(bǔ)償即可，由于明通公司管道飽和蒸汽壓力在0.3－0.7MPa范圍，壓力變送器的量程選擇1MPa即可。 </p> <p> （3）顯示儀表選擇 </p> <p> 顯示儀表智能流量顯示儀，具有穩(wěn)壓補(bǔ)償、瞬時流量顯示和累積流量積算功能。隨著工業(yè)的發(fā)展，對流量測量的準(zhǔn)確度和范圍要求越來越高，為了適應(yīng)多種用途，各種類型的流量計相繼問世。陜西金屬管浮子流量計制造商</p><p style="text-indent:25px">一體型儀表將孔板和浮子流量計組裝在短管段上，直接裝到待測管道，安裝方便。陜西金屬管浮子流量計制造商</p><p> 電磁流量計簡單說是由流量傳感器變送器組成的。電磁流量計的安裝要求是一定要安裝在管路的較低點(diǎn)或者管路的垂直段，但是一定是在滿管的情況下，對直管段要求是前5D后3D，這樣才能保證電磁流量計的使用和對精度的要求。 </p> <p> 電磁流量計的測量原理不依賴流量的特性，如果管路內(nèi)有一定的湍流與漩渦產(chǎn)生在非測量區(qū)內(nèi)（如：彎頭、切向限流或上游有半開的截止閥）則與測量無關(guān)。如果在測量區(qū)內(nèi)有穩(wěn)態(tài)的渦流則會影響測量的穩(wěn)定性和測量的精度，這時則應(yīng)采取一些措施以穩(wěn)定流速分布： </p> <p> 1. 增加前后直管段的長度;2. 采用一個流量穩(wěn)定器;3. 減少測量點(diǎn)的截面。陜西金屬管浮子流量計制造商</p><p
