信號(hào)傳輸電纜長(zhǎng)度的題目傳感器(即電極)與轉(zhuǎn)換器之間的連接電纜愈短愈好。但有些現(xiàn)場(chǎng)受安裝環(huán)境位置的限制，河南金屬轉(zhuǎn)子流量計(jì)廠，轉(zhuǎn)換器與傳感器的間隔較遠(yuǎn)，這時(shí)要考慮連接電纜的最大長(zhǎng)度題目。傳感器與轉(zhuǎn)換器之間的連接電纜的最大長(zhǎng)度又由電纜的分布電容和被測(cè)流體的電導(dǎo)率決定。實(shí)際使用中，當(dāng)被測(cè)流體的電導(dǎo)率是在一定的范圍之間，因此就決定了電極與轉(zhuǎn)換器之間電纜的最大長(zhǎng)度。當(dāng)電纜長(zhǎng)度超過最大長(zhǎng)度時(shí)，由電纜分布電容引起的負(fù)載效應(yīng)就成了題目。為防止這種情況發(fā)生，使用雙芯兩層屏蔽電纜，由轉(zhuǎn)換器提供低阻抗電壓源使內(nèi)側(cè)屏蔽與芯線得到相同的電壓，以形成屏蔽，即使芯線與屏蔽之間有分布電容存在，但芯線與屏蔽是同電位，則兩者之間就無電暢通流暢過，也無電纜的負(fù)載效應(yīng)存在，河南金屬轉(zhuǎn)子流量計(jì)廠，因此可延長(zhǎng)信號(hào)電纜最大長(zhǎng)度，河南金屬轉(zhuǎn)子流量計(jì)廠。另外，還可用特殊信號(hào)傳輸電纜延長(zhǎng)轉(zhuǎn)換器與傳感器之間的最大長(zhǎng)度。

精度高由于V錐結(jié)構(gòu)無可動(dòng)部件,使得V錐具有很好的重復(fù)性,一般小于0.1%。由于量程比寬,即它的線性度好,從而使其精度較高。根據(jù)GB17167-2006《用能單位能源計(jì)量器具配備和管理通則》規(guī)定,用于能源計(jì)量的流量計(jì)準(zhǔn)確度等級(jí)要求為:煤氣和天然氣為2.0級(jí)。所以在測(cè)試分離器出口的氣體測(cè)量中,在10∶1的量程范圍內(nèi),V錐加上差壓變送器及二次表的總體誤差不會(huì)低于1.5級(jí),完全能滿足計(jì)量要求。長(zhǎng)期性能好由于錐體的輪廓形狀限制了介質(zhì)的流動(dòng),流體沿著錐體形成了邊界層,這意味著錐體的邊緣不容易受不清潔的流體磨損,從而使開孔比β保持不變,使得流量計(jì)可以在很長(zhǎng)時(shí)間內(nèi)保持精度而不必校驗(yàn)。
