GF125 系列產(chǎn)品是第二代多變量壓力變化補(bǔ)償型 (PTI) 金屬密封質(zhì)量流量控制器和儀表,有著超快的響應(yīng)速度和超高的純度。作為個(gè)將 PTI 質(zhì)量流量控制技術(shù)引入市場的 GF125 系列產(chǎn)品限度降低了壓力和溫度波動(dòng)導(dǎo)致的過程氣體流量變化。一臺(tái)采用標(biāo)準(zhǔn) MultiFlo™ 技術(shù)的 MFC 即可滿足數(shù)千種氣體類型和各種量程組合的需求,無需從氣路上拆除 MFC 并且不影響精度。
結(jié)果:降低了氣體顯示屏尺寸和成本,這得益于省去了壓力調(diào)節(jié)器、壓力傳感器和相關(guān)硬件的使用并輔以行業(yè)的 PTI 性能以限度提高產(chǎn)率和生產(chǎn)效率。
