<th></th><td></td></tr> </tbody> </table> </section><p><span style="font-family: 宋體;">1、測(cè)量精確度高<br />※ 由于平衡流量傳感器具有對(duì)稱(chēng)多孔結(jié)構(gòu)特點(diǎn)，能對(duì)流場(chǎng)進(jìn)行平衡，降低了渦流、振動(dòng)和信號(hào)噪聲，流場(chǎng)穩(wěn)定性大大提高。其表體采用特制精密管道和取壓裝置，使精確度比傳統(tǒng)節(jié)流裝置提升了5-10倍。<br />※ 經(jīng)過(guò)實(shí)流標(biāo)定，傳感器精確度可達(dá)±0.30% - ±0.50%，適用于貿(mào)易計(jì)量場(chǎng)合。<br />※ 幾何尺寸檢驗(yàn)，傳感器精確度可達(dá)±0.50%、±1.00%，適用于過(guò)程控制場(chǎng)合。<br />※ A+K平衡流量計(jì)加工重復(fù)性*，與傳統(tǒng)節(jié)流裝置一樣，在實(shí)流標(biāo)定數(shù)據(jù)基礎(chǔ)上，可以實(shí)現(xiàn)幾何尺寸檢定。</span></p><p><span style="font-family: 宋體;">2、直管段要求低<br />※ 平衡流量傳感器能將流場(chǎng)平衡、調(diào)整穩(wěn)定，且壓力恢復(fù)比傳統(tǒng)孔板節(jié)流裝置快兩倍，大大縮短了對(duì)直管段的要求。<br />※ 直管段可以小至0.5D，采用平衡流量計(jì)可以省去大量直管段，尤其特殊昂貴材料的管道。</span></p><p><span style="font-family: 宋體;">3、壓力損失低<br />平衡流量計(jì)多孔對(duì)稱(chēng)的平衡設(shè)計(jì)，減少了渦流的形成和紊流摩擦，降低了動(dòng)能損失，在同工況、不降低差壓值的情況下，可比傳統(tǒng)節(jié)流裝置降低到1/2—1/3的壓力損失，可節(jié)省相當(dāng)多的運(yùn)行成本，是節(jié)能型儀表，值得信賴(lài)。</span></p><p><span style="font-family: 宋體;">4、量程比寬<br />※ 與傳統(tǒng)節(jié)流裝置相比，平衡流量計(jì)*提高了測(cè)量量程比。<br />※ 美國(guó)研究結(jié)果顯示：雷諾數(shù)大于5×10 4 時(shí)，選擇合適的孔徑參數(shù)，平衡流量傳感器量程<br />比無(wú)上限。<br />※ 根據(jù)工業(yè)測(cè)量需要，常規(guī)測(cè)量量程比為7:1-10:1，很多場(chǎng)合選擇合適的參數(shù)，可以做到20:1、<br />30:1或更高。</span></p><p><span style="font-family: 宋體;">5、耐臟污不易堵<br />多孔對(duì)稱(chēng)的平衡設(shè)計(jì)，減少了紊流剪切力和渦流的形成，從而大大降低了滯留死區(qū)的形成，保證臟污介質(zhì)順利通過(guò)多個(gè)孔，減小了流通孔被堵塞的機(jī)會(huì)。</span></p><p><span style="font-family: 宋體;">6、測(cè)量范圍寬<br />根據(jù)試驗(yàn)結(jié)果，平衡流量計(jì)的性能，使其流速可以到音速；其小雷諾數(shù)可低于200，大雷諾數(shù)大于10 7 ；β值可選0.25-0.90。</span></p><p><span style="font-family: 宋體;">7、重復(fù)性和*穩(wěn)定性好<br />※ 平衡流量傳感器能將流場(chǎng)平衡穩(wěn)定，使重復(fù)性大大提高，可達(dá)0.1%。<br />※ 平衡流量計(jì)多個(gè)流通孔分散受力，無(wú)銳角磨損，其β值*保持不變，*穩(wěn)定性高。<br />※ 整臺(tái)儀表無(wú)可動(dòng)部件，使用壽命比傳統(tǒng)節(jié)流裝置延長(zhǎng)5-10倍。</span></p><p><span style="font-family: 宋體;">8、適用范圍廣<br />※ 平衡流量計(jì)工作溫度、壓力取決于管道和法蘭的材質(zhì)和等級(jí)，分別可達(dá)850℃、42MPa或更高溫度、壓力介質(zhì)。<br />※ 適合液化氣體LNG、液態(tài)空氣、液氮、液氧、液氬、液化乙烯、液氫等，能有效防止氣化，測(cè)量效果好。<br />※ 平衡流量計(jì)可實(shí)現(xiàn)臟污、漿料等介質(zhì)的測(cè)量。<br />※ A+K平衡流量計(jì)左右*對(duì)稱(chēng)，可以十分方便地測(cè)量雙向流。</span></p><p><span style="font-family: 宋體;">9、AKET型號(hào)產(chǎn)品符合“鍋規(guī)”要求</span></p><p><span style="font-family: 宋體;">10、節(jié)能增效<br />※ A+K平衡流量計(jì)是一款典型的節(jié)能增效型差壓式流量計(jì)。<br />※ 流量計(jì)作為測(cè)量元件，本身也是耗能元件。流量計(jì)的運(yùn)行成本包括測(cè)量精確度成本和介質(zhì)輸送成本。測(cè)量精確度成本是因計(jì)量不準(zhǔn)確造成的貿(mào)易結(jié)算損失，對(duì)于貴重介質(zhì)而言，精確度成本十分重要。<br />※ 介質(zhì)輸送成本是介質(zhì)輸送過(guò)程消耗的能量，主要以測(cè)量元件造成的壓力損失為標(biāo)志，就液體等比重較大的流體而言，運(yùn)行輸送成本是一筆很大的開(kāi)支（泵消耗的電能）。<br /> </span></p> </div> <div id="j5txr7v" class="lyNyProDetail_ConTit"
