"Times New Roman"">一、金屬轉(zhuǎn)子流量計(jì)產(chǎn)品概述

"Times New Roman"">金屬管浮子流量計(jì)是工業(yè)自動(dòng)化過程控制中常用的一種流量測(cè)量?jī)x表，它具有壓損小，
mso-hansi-font-family:"Times New Roman"">檢測(cè)范圍大（量程比10:1 "Times New Roman"">），使用方便等特點(diǎn)，它可用來測(cè)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(zhì)流量測(cè)量。
H mso-hansi-font-family:"Times New Roman"">Ｗ50 "Times New Roman"">系列金屬管浮子流量計(jì)有就地顯示型和智能遠(yuǎn)傳型，帶有指針顯示，瞬時(shí)流量，累積流量，液晶顯示，上下限報(bào)警輸出，累積脈沖輸出，標(biāo)準(zhǔn)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(zhì)量的MCU mso-hansi-font-family:"Times New Roman"">微處理系統(tǒng)，保證了流量計(jì)在各種應(yīng)用場(chǎng)所的優(yōu)良性能。
mso-hansi-font-family:"Times New Roman"">多年來金屬管流量計(jì)的各種優(yōu)良性能和可靠性，以及較好的性能價(jià)格比廣泛受到了石化、鋼鐵、電力、冶金、輕工等行業(yè)的青睞。

"Times New Roman"">二、金屬轉(zhuǎn)子流量計(jì)結(jié)構(gòu)原理

1 mso-hansi-font-family:"Times New Roman"">、結(jié)構(gòu)
HW50 mso-hansi-font-family:"Times New Roman"">系列金屬管浮子流量計(jì)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(cè)量室

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

"Times New Roman"">被測(cè)介質(zhì)自下而上經(jīng)錐形測(cè)量管時(shí)浮子的上下端產(chǎn)生差壓形成上升的力，當(dāng)浮子所受上升力大于浸在流體中浮子重量，浮子便上升，環(huán)隙面積就隨之增大，環(huán)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(shí)，浮子便穩(wěn)定在某一高度。浮子位置的高低即對(duì)應(yīng)著被測(cè)介質(zhì)流量的大小。浮子內(nèi)置磁鋼，在浮子隨介質(zhì)上下移動(dòng)時(shí)，磁場(chǎng)隨浮子的移動(dòng)而變化。
a mso-hansi-font-family:"Times New Roman"">、對(duì)于就地型，由就地指示器中的旋轉(zhuǎn)磁鋼與浮子內(nèi)磁鋼耦合，而發(fā)生轉(zhuǎn)動(dòng)，同時(shí)帶動(dòng)指針，通過刻度盤指示出此時(shí)的流量大小。
 對(duì)于智能型，由智能型指示器中的一個(gè)固態(tài)磁傳感器將磁場(chǎng)的變化轉(zhuǎn)化成電信號(hào)，經(jīng)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。
