一、概述
1）产品种类及适用领域
SBL数显靶式流量计是在传统靶式流量计测量原理的基础上，充分利用其最优秀的特点，结合新型传感器技术和
现代数字技术上研制、开发而成的全新型力感应靶式流量计，它既具有传统靶式、孔板、涡街等流量计无可动部件
的特点，同时又具有与容积式流量计相媲美的测量准确度，加之其特有的抗干扰，抗杂质性能，轻便又可靠的特点，
广泛使用于石油、化工、能源、食品、环保、水利等各个领域。从其使用后的效果上看，SBL数显靶式流量计具有极
为广阔的适用性。
即：
·适用于各种管径：从Φ15～Φ2000mm至更大
·适用于高低温介质：从-196℃～+700℃
·适用于高压力工况：从0～70Mpa（表压）
2）产品特点
·能准确测量各种常温、高温、低温工况下的液体、气体、蒸汽，粘稠介质及各种流体介质的流量
·灵敏度极高，能测量超小流量，其可测量低流速为0.08m/s
·无可动部件，使用安全可靠
·计量准确，精度高，总量测量可达0.2%
·测量范围宽，最大测量范围可达1∶30
·重复性好，一般为0.1～0.08%，测量快速
·压力损失小，仅为标准孔板的1/2△P左右
·可采用干式标定方法，即法码挂重法
·可根据实际需要更换受力元件来改变测量流量范围
·能在线直读示值，又能运传发信
·安装简单方便，极易维护
二、结构及工作原理
1)结构：
SBL数显靶式流量计主要由测量管（壳体），受力元件，感应元件（力传感器，压力传感器，温度传感器），
过渡部件（根据温度，压力而增减），积算显示和输出部分，其结构如下图：
