Flow Switch/Flow Controller
A flow switch is a control switch. It can monitor the flow or non-flow of water, oil, gas and other media in the pipeline and perform opening or closing actions. The flow switch can set an upper limit or a lower limit. When the flow reaches the limit value, the flow switch sends a signal or an alarm. The system will run or stop to avoid or reduce the dry burning of the host.
Common applications of flow switches include: pump protection, cooling water or heat exchanger, drain flow, safety valve tracking, etc. Generally, systems that require flow will use flow switches.
The main function of the flow switch is to trigger the alarm system when the flow of the medium reaches or exceeds the set value, and send an alarm signal to the control unit. When the control unit receives this signal, it will issue a corresponding instruction to shut down or start the operation of the system, thereby realizing the role of flow control. It is widely used in medium pipelines to monitor the size of water flow in water systems.

Main Functions of a Flow Switch
1. Flow monitoring
One of the main functions of flow switches is to monitor the flow of fluid media. In the industrial production process, various fluid media need to be monitored in real time to ensure the normal operation of the production process. Flow switches can sense the speed, pressure and other parameters of fluid media in real time, and convert these parameters into electrical signals for data processing and analysis by the control system.
2. Flow control
Flow switches also have the function of flow control. In the industrial production process, the flow of fluid media needs to be accurately controlled according to production needs and process requirements. Flow switches can adjust the flow of fluid media by controlling the switch state of the valve to meet the actual needs of the production process.
3. Flow protection
Flow switches also have the function of protecting equipment in industrial production. When the flow of fluid media is abnormal, such as too large or too small, it may cause damage to production equipment. Flow switches can detect these abnormalities in time and take corresponding measures, such as closing valves or alarm prompts, to avoid equipment damage and safety accidents.
4. Energy management
Flow switches also play an important role in energy management. By monitoring the flow of fluid media, the energy consumption of equipment can be understood, and then the energy utilization of the production process can be optimized. Flow switches can also be combined with energy management systems to achieve remote monitoring and management and improve the efficiency and effectiveness of energy management.
What is a Flow Switch?
Like other switches, a flow switch is also a device used to connect and disconnect current in a circuit. In industrial automation systems, flow switches play a vital role in monitoring and controlling the flow rate of process media such as steam, liquids and gases. Flow switches provide on/off flow control of process media by triggering the action of various machines within the system, helping to maintain a safe and manageable flow rate.
