該流量計帶一體化變送器，節(jié)約成本。
Promass E系列質(zhì)量流量計采用科氏力原理，節(jié)約成本，贏得了良好的聲譽(yù)。該流量計帶一體化Promass 40變送器，適用于低端測量場合，提供高精度的液體與氣體流量測量，應(yīng)用范圍廣泛。
模塊化的設(shè)備與操作概念，帶來更高的效率。
一體化結(jié)構(gòu)的流量測量，更少測量點－多元化測量（流量，溫度）
平衡的雙管測量系統(tǒng)設(shè)計，抗震性好。
堅固的設(shè)計，不受外部管道作用力影響。
無需進(jìn)出口直管段，安裝簡便。
科氏力測量原理不受液體物理屬性影響，例如粘度和密度。
極為精確地測量液體和氣體，例如添加劑、石油、油脂、酸、堿、涂料、油漆和天然氣。
流體溫度最高可達(dá) +140 °C (+284 °F)
過程壓力可以高達(dá)100 bar (1450 psi)
質(zhì)量流量測量可達(dá)180 t/h (6600 lb/min)
