主要技术指标
1.无可动部件，运行可靠，性能较好，使用寿命长。
2.测量被测流体，不直接接触传感器，性能稳定。
3.输出信号是与流量成正比的脉冲信号或输出4~20mA标准电流信号。
4.压力损失较少，故比差压流量计具有节能特点。
5.测量量程比大，可达1：10。而差压式只有1：3。
6.结构简单而牢固，安装方便，维修费用极少。
本系列本安防爆型产品经国家级仪器仪表防爆安全监督检验站(NEPSI)检验认可，符合国家标准GB3896.1/4-83的规定，其防爆标志为ExibⅡCT1-6，防爆合格证为CXB00285。本产品与关联设备-安全栅配合使用构成本安全防爆系统后，可应用于相应爆炸性危险场所。用户在现场安装使用，须注意下列事项：
产品外壳设有接地端子，用户在使用产品时，须可靠接地；
本安型涡街流量传感器必须与经防爆检验机构认定的安全栅配接才能构成本安防爆系统；
传感器与安全栅本安端之间的连接电缆为三芯屏蔽电缆(电缆必须有绝缘护套)芯线截面0.5mm2。其屏蔽层在安全场所单端接地，其电缆布线尽可能排除电磁干扰的影响并使电缆分布参数控制在0.05F之内；
