"Times New Roman"">金属转子流量计- "Times New Roman"">江苏华伟远航自动化仪表有限公司

"Times New Roman"">一、金属转子流量计产品概述

"Times New Roman"">金属管浮子流量计是工业自动化过程控制中常用的一种流量测量仪表,它具有压损小,
mso-hansi-font-family:"Times New Roman"">检测范围大(量程比10:1 "Times New Roman"">),使用方便等特点,它可用来测量液体,气体以及蒸汽的流量,特别适宜低流速小流量的介质流量测量。
H
mso-hansi-font-family:"Times New Roman"">W50 "Times New Roman"">系列金属管浮子流量计有就地显示型和智能远传型,带有指针显示,瞬时流量,累积流量,液晶显示,上下限报警输出,累积脉冲输出,标准的二线制4-20mA mso-hansi-font-family:"Times New Roman"">电流输出等多种形式,为用户提供了非常广阔的选择空间。另外该仪表采用高质量的MCU mso-hansi-font-family:"Times New Roman"">微处理系统,保证了流量计在各种应用场所的优良性能。
mso-hansi-font-family:"Times New Roman"">多年来金属管流量计的各种优良性能和可靠性,以及较好的性能价格比广泛受到了石化、钢铁、电力、冶金、轻工等行业的青睐。

"Times New Roman"">二、金属转子流量计结构原理

1 mso-hansi-font-family:"Times New Roman"">、结构
HW50
mso-hansi-font-family:"Times New Roman"">系列金属管浮子流量计主要由三大部分组成
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"">、锥形测量室

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

"Times New Roman"">被测介质自下而上经锥形测量管时浮子的上下端产生差压形成上升的力,当浮子所受上升力大于浸在流体中浮子重量,浮子便上升,环隙面积就随之增大,环隙处流体流速立即下降,浮子上下端差压降低,作用于浮子的上升力亦随着减少,直到上升力等于浸在流体中浮子重量时,浮子便稳定在某一高度。浮子位置的高低即对应着被测介质流量的大小。浮子内置磁钢,在浮子随介质上下移动时,磁场随浮子的移动而变化。
a
mso-hansi-font-family:"Times New Roman"">、对于就地型,由就地指示器中的旋转磁钢与浮子内磁钢耦合,而发生转动,同时带动指针,通过刻度盘指示出此时的流量大小。
 
对于智能型,由智能型指示器中的一个固态磁传感器将磁场的变化转化成电信号,经A/D mso-hansi-font-family:"Times New Roman"">变换、微处理器,D/A "Times New Roman"">输出,LCD液晶显示,来显示出流量的大小及累积流量。

"Times New Roman"">三、金属转子流量计主要特点
