style="text-indent:25px">對于電磁流量計(jì)廠家來說，和客戶溝通是為了做好電磁流量計(jì)選型工作，這個(gè)時(shí)候就肯定會(huì)問到對方需要什么樣的連接方式。除了清楚連接方式之外，還要清楚多大的法蘭，什么標(biāo)準(zhǔn)尺寸的法蘭;什么樣的螺紋，內(nèi)螺紋還是外螺紋，幾寸的螺紋等等。正確的選擇連接方式，是保證正常使用電磁流量計(jì)的前提。安裝電磁流量計(jì)(如渦街電磁流量計(jì))時(shí)，用戶需另配一對標(biāo)準(zhǔn)法蘭焊在前后管道上。不允許帶電磁流量計(jì)焊接!安裝時(shí)，法蘭間的密封墊片不能凹入管道內(nèi)。渦街測量過熱蒸汽：想要計(jì)量準(zhǔn)確只有采用溫度壓力補(bǔ)償?shù)臏u街流量計(jì)才能做到真正準(zhǔn)確計(jì)量。</p><div
