RM系列 Rate-Master®轉子流量計是具有多種獨特功能的直讀式精密流量計,價格低,用途廣泛。

讀數容易 --直讀式刻度消除了單位換算的麻煩。刻度線印在鋁板上,表面覆有環氧樹脂,指示管兩側都標有刻度線。特別整合的浮子流向導杆使浮子穩定以避免損壞或漂移。在白色的背景襯托下,浮子清晰可見。

結搆精密 --所有Rate-Master@流量計都由堅固、透明、防碎的聚碳酸脂塑料注模而成,內部精密制造的錐管使得流量計精確度高,重復性好。塑料主體固定在不鏽鋼后板上,接管螺紋被牢固地插入焊接可承受較大扭矩。還可選用黃銅閥或不鏽鋼閥(訂購是注明BVSSV)來進行精確的流量調整。在真空應用場合,RMA型可選用頂部閥門(需注明TMV)。RMA系列的精度為±4%RMB系列的精度為±3%RMC系列的精度為±2%

安裝簡單 --Rate-Master@流量計可以安裝在面板上,也可以嵌入安裝。嵌入安裝時,斜角可以自動地把儀表固定在面板合適的位置上,表面安裝時,還可以釆用管線來安裝固定。帶有所有的安裝部件,安裝操作說明書。

通用式主體 --Rate-Master@流量計主體可方便地互換,互換時只需從后板上取下主體并用另外的O型環在進出口處密封即可,不會影響管道。在實驗室或工廠里,當所需的量程范圍不衕時,可互換性是非常有用和方便的。

清潔方便--只需松開四個螺釘即可把流量計塑料管身從不鏽鋼后板上取下,而且不影響管身螺紋的連接。打開滑蓋和塞子,用水和肥皂清洗流量管,然后重新安裝好,就是這簡單。
