一、概述
3051系列变送器是根据电磁感应定律，按JB/T9248－1999标准制造，用于测量管道中导电液体的体积流量，如水、污水、泥浆、矿浆、酸、碱、盐液体及食品浆液等。在石油化工、矿冶、煤炭、水利工程给排水、污水处理等行业中广泛应用。本公司生产的电磁流量计有三种：一体型、分体型和4－20mA输出型（不带显示）。
二、工作原理
3051系列变送器所依据的基本理论是法拉第电磁感应定律。当导体切割磁力线运动时，导体内将产生感应电动势。根据该原理，可测量管内流动的导电流体的体积，如图1所示，导电流体流动的方向与电磁场的方向垂直，在导管垂直方向施加一个交变的磁场，并在有绝缘衬里的导管内壁两侧安装一对电极，两电极的连线既与导管轴线垂直，又与磁场方向垂直，当导电液体流经导管时，因切割磁力线，两个电极上就产生感应电动势Uk。传感器导管内径D是固定的，通过励磁线圈的励磁电流是恒定值时，磁感应强度B也是恒定值，因此，平均流速V或流量Q（Qv=πD2/4.V）与感应电动热Ue的大小成正比例关系。
三、产品特点
