DTFW系列液體變面積流量計(jì)測量水的流量，測量精度為全尺寸的±2%。 持久的金屬結(jié)構(gòu)確保了巨大的兼容性和強(qiáng)度，以承受系統(tǒng)壓力高達(dá)3000 psig (200 bar)。 可提供1/4"、1/2"和1"連接，結(jié)構(gòu)可選用優(yōu)質(zhì)黃銅或不銹鋼。 來預(yù)先校準(zhǔn)水平在線安裝。
耐用的金屬結(jié)構(gòu)確保了高可靠性和強(qiáng)度，可承受高達(dá)3000 psig (200 bar)的系統(tǒng)壓力 防震結(jié)構(gòu)，不同于玻璃管可變面積流量計(jì)，使用壽命長可在高溫、高振動(dòng)、易沖擊的環(huán)境下精確預(yù)成型
