使用说明：
1、串联信号灯或报警器（负载电流不能大于0.3A，大于0.3A请配合中间继电器使用）接PLC可以直接负载开关，不分正负
2、控制水泵、电机之类：（750W以下配带中间继电器配合使用，不可以直接负载） （750W以上配带中间继电器跟交流接触器使用，不可直接负载开关） 不分正负
3、重力式水流开关只能垂直安装，水流从下而上流过。
特别提示：开关不能直接负载在交流接触器上，只能负载中间继电器。
技术参数：
1、启动流量：1.5L/min—2L/min
2、最大流量：12L/min
3、正常工作压力：0.005-1.0MPa
4、最大压力：1.5MPa
5、安装方向：垂直安装
6、最高耐温：100度
7、工作电压：DC5V-DC24V
注意事项
1、避免开关靠近磁性物体
2、箭头指示为水流方向
3、如负载电流超过开关最大负载电流，必须加装中间继电器，开关不可以直接带接触器。
4、杂质会影响水流开关性能，建议加装前置滤网。
5、铁块亦会对水流开关产生影响，建议避开。
The gravity type water flow switch uses the bottom-up movement of the copper float to drive the permanent magnet to cooperate with the reed switch to output the switch signal (0/1), and it is reset by the gravity of the permanent magnet float. Compared with the mechanical spring, it is more stable and reliable. Longer life and smaller starting flow rate. All copper material.
Instructions for use:
1. Serial signal lights or alarms (load current should not be greater than 0.3A, please cooperate with intermediate relays if greater than 0.3A) when connected to PLC, you can directly load switch, regardless of positive or negative
2. Control water pumps, motors, etc.: (with intermediate relays below 10W for use, and no direct load) (with intermediate relays and AC contactors above 10W, no direct load switching) No distinction between positive and negative
3. The gravity water flow switch can only be installed vertically, and the water flows from bottom upward.
Special note: The switch cannot be directly connected with the AC contactor, only the relay.
Technical parameter:
1. Starting flow: 1.5L/min-2L/min
2. Maximum flow: 12L/min
3. Normal working pressure: 0.005-1.0MPa
4. Installation direction: vertical installation
5. The highest temperature resistance: 120 degrees
6. Working voltage: DC5V-DC24V
Precautions
1. Avoid switches close to magnetic objects
2. The arrow indicates the direction of water flow
3. If the load current exceeds the maximum load current of the switch, an intermediate relay must be installed, and the switch cannot be directly equipped with a contactor.
4. Impurities will affect the performance of the water flow switch, it is recommended to install a pre-filter.
5. The iron block will also affect the water flow switch, it is recommended to avoid it.
