In order to change the behindhand state in measurement of natural gas of liaohe oil field , we make the technique reformation , using the normal hole - board , intelligent sensor , natural gas compression factor , arithmetic of volume flux and compensatory technology 為了改變遼河油田天然氣落后的計(jì)量狀態(tài),我們采用標(biāo)準(zhǔn)孔板、智能傳感器、國(guó)際標(biāo)準(zhǔn)天然氣壓縮因子、體積流量算法和補(bǔ)償技術(shù)進(jìn)行天然氣計(jì)量技術(shù)改造。
Adopt full chinese large screen with backlight lcd liquid crystal display , and have pagin display function can display instantaneous temperature , pressure , flow , super - compression factor , date and time , instantaneous flow , and accumulate flow and so on . can with serial communication interface 根據(jù)選型功能的不同及現(xiàn)場(chǎng)控制的需要,操作器可有一個(gè)報(bào)警al1或兩個(gè)報(bào)警al1 al2輸出,報(bào)警值對(duì)應(yīng)于反饋或測(cè)量信號(hào)的顯示值pv 。
Due to the component of natural gas is very complex in different zone of our country , the product has taked on special design , it set up moore component factor of thirteen kinds , which offer user to select and setup , so as to satisfy measurement for contains various component natural gas , at the same time established many take - pressure way in order to suit to different measure device , and have automatic calculate and display super - compression factor function A q型操作器輸出svout : 010ma 420ma 05v 15v信號(hào),可直接驅(qū)動(dòng)執(zhí)行機(jī)構(gòu)變頻器或再由伺服放大器去驅(qū)動(dòng)電動(dòng)調(diào)節(jié)閥門或由電氣轉(zhuǎn)換器和閥門定位器去驅(qū)動(dòng)氣動(dòng)薄膜閥。操作器處于自動(dòng)工作狀態(tài)時(shí),其信號(hào)輸入svin和操作輸出信號(hào)相當(dāng)于是直通的。以實(shí)現(xiàn)dcs系統(tǒng)或調(diào)節(jié)器對(duì)執(zhí)行機(jī)構(gòu)的自動(dòng)控制。
