磁力联动装置，UL认证
V7系列Flotect流量开关是一种廉价的流量开关，可与兼容液体一起使用，在出现流动或无流动情况时启动或停止电子操作设备。设计为标准防风雨设计，符合NEMA 4X。
产品应用
当通过加热线圈的气流发生故障时，锅炉流量的证明会关闭燃烧器保护泵、电机和其他设备，防止低流量或无流量液体冷却发动机，当冷却液流动中断时的机器和处理
特点
磁力驱动开关设计提供了优越的性能
具有一个自由摆动的叶片，它吸引了固体金属开关体内的磁铁，通过一个简单的杠杆臂驱动一个速动开关，没有波纹管、弹簧或密封件失效
下阀体是实体加工的确保无泄漏点的金属棒料，无论机组运行多长时间
坚固的叶片设计是刚性的，并且可在现场调节设定值
