YONGSUNG韩国龙声水位自动调节开关选型：
龙声YSFS系列水位自动调节开关特点：
.小型，8个管脚的插座式结构，施工检修方便。
.半导体方式，寿命为半永久性。
.完全自动调整水位，防止有关的机械故障。
YONGSUNG韩国龙声YSFS系列水位开关使用方法：
.当继电器部门和电极棒（座）25㏀以上时请用高灵敏度水位器。
.When Relay Unit nd electrode holder is above 25㏀, select high sensitivity.
.水箱上设置电极棒，并把水位开关（继电器部分）设置在盘上与接触器连接。
.Install electrode holder to water tank and Floatless Switch (Relay Unit) to panel respectively, and then
connect to magnet switch.
.选定的接触器，一定要与泵的的电动机容量配合。
.Select Magnet Switch according to pump motor capacity.
.电极棒采用不锈钢或者黄铜直径为φ4～5比较好。
.Use stainless rod or brass road and 4to5φ is suitable.
.电极棒的长度应在选定上限于下限之后确定。
.As to the length of electrode abr, select max. and min. limits and set it.
