本公司 常用差壓變送器根據(jù)以下幾點(diǎn)選型：
1、測(cè)量范圍、需要的精度及測(cè)量功能；
2、測(cè)量?jī)x表面對(duì)的環(huán)境，如石油化工的工業(yè)環(huán)境，有可燃（有毒）和爆炸危險(xiǎn)氣氛的存在，有較高的環(huán)境溫度等；
3、被測(cè)介質(zhì)的物理化學(xué)性質(zhì)和狀態(tài)，如強(qiáng)酸、強(qiáng)堿、粘稠、易凝固結(jié)晶和氣化等工況；
4、操作條件的變化，如介質(zhì)溫度、壓力、濃度的變化。有時(shí)還要考慮到從開(kāi)車(chē)到參數(shù)達(dá)到正常生產(chǎn)時(shí)，氣相和液相濃度和密度的變化；
5、被測(cè)對(duì)象容器的結(jié)構(gòu)、形狀、尺寸、容器內(nèi)的設(shè)備附件及各種進(jìn)出口料管口都要考慮，如塔、溶液槽、反應(yīng)器、鍋爐汽包、立罐、球罐等；
6、其他要求，如環(huán)保及衛(wèi)生等要求；
7、工程儀表選型要有統(tǒng)一的考慮，要求盡可能地減少品種規(guī)格，減少備品備件，以利管理；
8、工藝商的具體要求。
9、實(shí)際的工藝情況：
1）考慮被測(cè)對(duì)象是屬于哪一類設(shè)備。如槽、罐類，槽的容積較小，測(cè)量范圍不會(huì)太大，罐的容積較大，測(cè)量范圍可能較大；
2）要看介質(zhì)的物化性質(zhì)及潔凈程度，常規(guī)的差壓式變送器及浮筒式液位變送器，還要對(duì)接觸介質(zhì)部分的材質(zhì)進(jìn)行選擇；
3）對(duì)有些懸浮物、泡沫等介質(zhì)可用單法蘭式差壓變送器。有些易析出、易結(jié)晶的用插入式雙法蘭式差壓變送器；
4）對(duì)高黏度的介質(zhì)的液位及高壓設(shè)備的液位，由于設(shè)備無(wú)法開(kāi)孔，可選用放射液位計(jì)來(lái)測(cè)量；[4]
5）除了測(cè)量方法上和技術(shù)上問(wèn)題外，還有儀表投資問(wèn)題。
綜上所述，變送器的選型，從技術(shù)上要可行，經(jīng)濟(jì)上要合理，管理上要方便。
在諸類儀表中，變送器的應(yīng)用廣泛、普遍，變送器大體分為壓力變送器和差壓變送器。變送器常用來(lái)測(cè)量壓力、差壓、真空、液位、流量和密度等。變送器有兩線制和四線制之分，兩線制變送器尤多；有智能和非智能之分，智能變送器漸多；有氣動(dòng)和電動(dòng)之分，電動(dòng)變送器居多；另外，按應(yīng)用場(chǎng)合有本安型和隔爆型之分；按應(yīng)用工況變送器的主要種類如下：
低（微）壓/低差壓變送器；
中壓/中差壓變送器；
高壓/高差壓變送器；
絕壓/真空/負(fù)壓差壓變送器；
高溫/壓力、差壓變送器；
耐腐蝕/壓力、差壓變送器；
易結(jié)晶/壓力、差壓變送器
