Main technical parameters
Wiring diagram
The FCT type flow switch can easily set the flow alarm node, unscrew the protective thread, and adjust the bottom knob with a threaded knifeSet the flow alarm point. For flow switches with output forms of PNP, NPN, and relays, the meaning of their LED indicators is as follows: - Red light on, flow rate lower than set (transient not conducting/relay not acting) - Yellow w light on, Flow rate equal to or higher than set (transient conduction/relay action) - The flow rate of the yellow and green lights exceeds the set level (green lights 1, 2, 3, or 4 lights up together with the yellow light)

Knowledge extension:
A brief introduction to flow switches
The flow switch is mainly installed online or plug-in to monitor the water flow in the water system of water, gas, oil, and other medium pipelines When the water flow rate is higher or lower than a certain setting, an alarm signal is triggered and transmitted to the unit After observing this signal, the system can make corresponding instructions Avoid or reduce the ^ ^ dry burn ^ ^ of the host
Set the upper or lower limit of the flow switch When the flow reaches the limit value, the flow switch will send a signal or alarm, and the system will run or stop Systems that typically require flow will use flow switches
The working principle of the flow switch:
The working principle of the flow switch is when there is water flowing through the flow switch and the water flow rate
When the water flow is ≥ 1.0L/min, the magnetic core in the water flow switch is displayed by the water flow The magnetic core display drives the magnetic source to generate a magnetron function, causing the water flow switch to output an ^ ^ open ^ ^ signal This signal is input to the device control system, which implements control functions When the water flow rate is less than the initial flow rate, the flow switch outputs a ^ ^ close ^ ^ signal The control system products the candidate control effect as described above In other words, when the water flow switch in the pipeline is greater than 1L/min, the magnetic core shifts and drives under the action of water flow The source generates magnetic control function, causing the sensor to output a ^ ^ 1 ^ ^ ^ switch signal, which is input to the device control system to receive the purpose of water flow control after power amplification When the flow rate is less than 1L/min, the magnetic core drives the magnetic source back under the rust of the reset spring, causing the sensor to output a ^ ^ 0 ^ ^ switch signal to stop the system operation
Advantages of flow switches:
The low flow (volume) effect of the water flow switch
2. The flow switch has a simple structure and a small contact surface
3. The flow switch is also suitable for low content debris flow
When the flow switch is blocked by special fabrics, it can be removed online
