靶式流量計(jì)正確選型才能保證靶式流量計(jì)更好的使用。選用什么種類的靶式流量計(jì)應(yīng)根據(jù)被測(cè)流體介質(zhì)的物理性質(zhì)和化學(xué)性質(zhì)來(lái)決定?使靶式流量計(jì)的通徑、流量范圍、和輸出方式等都能適應(yīng)被測(cè)流體的性質(zhì)和流量測(cè)量的要求。 </p> <p> 1、精密功能檢查; </p> <p> 精度等級(jí)和功能根據(jù)測(cè)量要求和使用場(chǎng)合選擇儀表精度等級(jí)，做到經(jīng)濟(jì)合算。比如用于貿(mào)易結(jié)算、產(chǎn)品交接和能源計(jì)量的場(chǎng)合，應(yīng)該選擇精度等級(jí)高些，如1.0級(jí)、0.5級(jí)，或者更高等級(jí); 用于過(guò)程控制的場(chǎng)合，根據(jù)控制要求選擇不同精度等級(jí);有些**是檢測(cè)一下過(guò)程流量，無(wú)需做精確控制和計(jì)量的場(chǎng)合，可以選擇精度等級(jí)稍低的，如1.5級(jí)、2.5級(jí)，甚至 4.0級(jí)，這時(shí)可以選用價(jià)格低廉的插入式靶式流量計(jì)。 </p> <p> 2、可測(cè)量的介質(zhì); </p> <p> 測(cè)量介質(zhì)流速、儀表量程與口徑測(cè)量一般的介質(zhì)時(shí)，靶式流量計(jì)的滿度流量可以在測(cè)量介質(zhì)流速0.1-12m/s范圍內(nèi) 選用，范圍比較寬。選擇儀表規(guī)格(口徑)不一定與工藝管道相同，應(yīng)視測(cè)量流量范圍是否在流速范圍內(nèi)確定，即當(dāng)管道流速偏低，不能滿足流量?jī)x表要求時(shí)或者在此流速下測(cè)量準(zhǔn) 確度不能保證時(shí)，需要縮小儀表口徑，從而提高管內(nèi)流速，得到滿意測(cè)量結(jié)果。為使電磁流量計(jì)的傳感器小型化和改善信噪比而出現(xiàn)用非均勻磁場(chǎng)和低頻勵(lì)磁方式的電磁流量計(jì)。橢圓齒輪流量計(jì)**</p><p
