幾種檢定方式的選取流量測(cè)量儀表的檢定，通常采用實(shí)流檢定和干式檢定兩種方式。采用何種方式檢定流量儀表取決于計(jì)量系統(tǒng)對(duì)測(cè)量不確定度的要求、被檢流量計(jì)的類型、用途、所具備的檢定條件、檢定所需費(fèi)用等諸多因素。一般，用于液體計(jì)量的流量儀表（如原油和水計(jì)量儀表）基本上采用實(shí)流檢定，而氣體計(jì)量的流量儀表（如天然氣貿(mào)易結(jié)算用的差壓式流量儀表）絕大多數(shù)采用干式檢定方式，只有極少數(shù)采用臨界流噴嘴在線實(shí)流檢定或離線檢定。
其次，幾乎所有的電子類產(chǎn)品都不得不通過電磁兼容測(cè)試認(rèn)證，這是和組織的技術(shù)壁壘，產(chǎn)品要想進(jìn)入這些市場(chǎng)必須有強(qiáng)制性認(rèn)證，這方面世界各個(gè)地區(qū)都有各自的標(biāo)準(zhǔn)。電磁兼容認(rèn)證的步驟苛刻龐雜，正式的產(chǎn)品認(rèn)證需要大量測(cè)試設(shè)備和測(cè)試過程，費(fèi)金耗時(shí)。在產(chǎn)品研發(fā)設(shè)計(jì)的各個(gè)階段中都應(yīng)盡早發(fā)現(xiàn)和解決各個(gè)級(jí)別的電磁兼容的問題，提升產(chǎn)品的過程質(zhì)量，避免后的產(chǎn)品認(rèn)證測(cè)試不通過，導(dǎo)致同樣費(fèi)金耗時(shí)的返工整改。（多說一句，電磁設(shè)備對(duì)人的影響屬于電磁兼容的范疇嗎？概念上講并不是，而且電磁對(duì)人的生理影響尚未有科學(xué)依據(jù)，所以還沒有劃歸到電磁兼容領(lǐng)域。

PLC
處理器(CPU)由控制器、運(yùn)算器和寄存器組成并集成在一個(gè)芯片內(nèi)。CPU通過數(shù)據(jù)總線總線、地址總線、控制總線和電源總線與存儲(chǔ)器、輸入輸出接口、編程器和電源相連接。
小型PLC的CPU采用8位或16位微處理器或單片機(jī)，如8031、M68000等，這類芯片價(jià)格很低；中型PLC的CPU采用16位或32位微處理器或單片機(jī)，如8086、96系列單片機(jī)等，這類芯片主要特點(diǎn)是集成度高、運(yùn)算速度快且可靠性高；而大型PLC則需采用高速位片式微處理器。
CPU按照PLC內(nèi)系統(tǒng)程序賦予的功能指揮PLC控制系統(tǒng)完成各項(xiàng)工作任務(wù)
