        "Times New Roman"">金屬轉子流量計- "Times New Roman"">江蘇華偉遠航自動化儀表有限公司

        "Times New Roman"">一、金屬轉子流量計產品概述

        "Times New Roman"">金屬管浮子流量計是工業自動化過程控制中常用的一種流量測量儀表,它具有壓損小,
        mso-hansi-font-family:"Times New Roman"">檢測范圍大(量程比10:1 "Times New Roman"">),使用方便等特點,它可用來測量液體,氣體以及蒸汽的流量,特別適宜低流速小流量的介質流量測量。
        H
        mso-hansi-font-family:"Times New Roman"">W50 "Times New Roman"">系列金屬管浮子流量計有就地顯示型和智能遠傳型,帶有指針顯示,瞬時流量,累積流量,液晶顯示,上下限報警輸出,累積脈沖輸出,標準的二線制4-20mA mso-hansi-font-family:"Times New Roman"">電流輸出等多種形式,為用戶提供了非常廣闊的選擇空間。另外該儀表采用高質量的MCU mso-hansi-font-family:"Times New Roman"">微處理系統,保證了流量計在各種應用場所的優良性能。
        mso-hansi-font-family:"Times New Roman"">多年來金屬管流量計的各種優良性能和可靠性,以及較好的性能價格比廣泛受到了石化、鋼鐵、電力、冶金、輕工等行業的青睞。

        "Times New Roman"">二、金屬轉子流量計結構原理

        1 mso-hansi-font-family:"Times New Roman"">、結構
        HW50
        mso-hansi-font-family:"Times New Roman"">系列金屬管浮子流量計主要由三大部分組成
        a
        mso-hansi-font-family:"Times New Roman"">、指示器(智能型指示器,就地指示器)
        b
        mso-hansi-font-family:"Times New Roman"">、浮子
        c
        mso-hansi-font-family:"Times New Roman"">、錐形測量室

        2 mso-hansi-font-family:"Times New Roman"">、工作原理

        "Times New Roman"">被測介質自下而上經錐形測量管時浮子的上下端產生差壓形成上升的力,當浮子所受上升力大于浸在流體中浮子重量,浮子便上升,環隙面積就隨之增大,環隙處流體流速立即下降,浮子上下端差壓降低,作用于浮子的上升力亦隨著減少,直到上升力等于浸在流體中浮子重量時,浮子便穩定在某一高度。浮子位置的高低即對應著被測介質流量的大小。浮子內置磁鋼,在浮子隨介質上下移動時,磁場隨浮子的移動而變化。
        a
        mso-hansi-font-family:"Times New Roman"">、對于就地型,由就地指示器中的旋轉磁鋼與浮子內磁鋼耦合,而發生轉動,同時帶動指針,通過刻度盤指示出此時的流量大小。
         
        對于智能型,由智能型指示器中的一個固態磁傳感器將磁場的變化轉化成電信號,經A/D mso-hansi-font-family:"Times New Roman"">變換、微處理器,D/A "Times New Roman"">輸出,LCD液晶顯示,來顯示出流量的大小及累積流量。

        "Times New Roman"">三、金屬轉子流量計主要特點

        1. mso-hansi-font-family:"Times New Roman"">適用于小管徑和低流速
        2.
        mso-hansi-font-family:"Times New Roman"">工作可靠、維護量小、壽命長
        3.
        mso-hansi-font-family:"Times New Roman"">對于下游直管段要求不高
        4.
        mso-hansi-font-family:"Times New Roman"">有較寬的流量范圍度10:1
        5.
        mso-hansi-font-family:"Times New Roman"">就地型指針指示接近于線性
        6.
        mso-hansi-font-family:"Times New Roman"">智能型指示器帶有LCD "Times New Roman"">液晶顯示,可顯示瞬時、累積流量,還可輸出脈沖、輸出報警
        7.
        mso-hansi-font-family:"Times New Roman"">帶有溫度補償
        8.
        mso-hansi-font-family:"Times New Roman"">有就地型、遠傳型、夾套型、防爆、耐腐等多種形式
