(1).測(cè)量渦流頻率的檢測(cè)元件，一般都設(shè)置在渦流發(fā)生器的內(nèi)部，與流體隔離，所以渦流流量傳感器可以對(duì)所有的流體進(jìn)行流量檢測(cè)。(2).在流體的通道上設(shè)置的渦流發(fā)生器是固定的，因此傳感器沒(méi)有運(yùn)動(dòng)部分，使傳感器長(zhǎng)期使用的可靠性得到保證。(3).因?yàn)樽璧K流體運(yùn)動(dòng)的只有一根渦流發(fā)生器，所以壓力損失小。(4).傳感器測(cè)量流體的溫度為-40——300℃，流體的較高壓力可達(dá)30MPa。(5).傳感器測(cè)定流速的范圍，液體較大為10m/s，氣體較大為90m/s。使用電子渦流流量傳感器時(shí)應(yīng)注意以下幾點(diǎn)：1.當(dāng)被測(cè)流體的流速偏低時(shí)，流體將產(chǎn)生不穩(wěn)定渦流，此時(shí)應(yīng)適當(dāng)減小管道的口徑以提高流速。2.當(dāng)測(cè)定附著性流體時(shí)，如果渦流發(fā)生器上附著過(guò)多的流體，將會(huì)使測(cè)量誤差增大。3.傳感器安裝時(shí)，應(yīng)設(shè)置在管道振動(dòng)小的位置，并固定在牢固可靠的支架上。重慶數(shù)顯溫控器</p></p><br
