External Hydraulic Brass Fuel Paddle Type Flow Switch
Production Description
Flow Switch Working Principle
Flow Detection:
- Mechanical Flow Switch: In a mechanical flow switch, a paddle or vane is placed inside the pipe where fluid flows. When fluid flows through the pipe, it pushes against the paddle, causing it to move.
- Electronic Flow Switch: In electronic flow switches, sensors such as ultrasonic, magnetic, or thermal sensors detect the flow without any moving parts.
Switch Activation:
- When the fluid flow reaches a certain threshold, the movement of the paddle (in a mechanical switch) or the sensor detection (in an electronic switch) causes the switch mechanism to change state. This could mean closing or opening an electrical circuit.
- If the flow stops or drops below the set threshold, the switch mechanism will revert to its original state.
Triggering an Action:
- The change in the switch mechanism triggers an action, such as sending an alert, turning on a pump, or shutting down equipment to prevent damage.
Feedback and Control:
- Some flow switches provide feedback to a control system, allowing for automated adjustments to the system based on real-time flow conditions.
Basic Components:
Sensing Element: This is the part of the switch that interacts with the fluid flow. It can be a paddle, vane, or sensor depending on the type of flow switch.
Switch Mechanism: The internal mechanism that changes state (e.g., opening or closing a circuit) when the sensing element detects flow or a lack of flow.
Output Signal: The action triggered by the switch, such as activating an alarm, shutting down equipment, or starting a pump.
Types of Flow Switches:
- Mechanical Flow Switches: Use a physical component, like a paddle or vane, to detect flow.
- Electronic Flow Switches: Use sensors, such as ultrasonic or magnetic sensors, to detect flow without moving parts.

Product Technical Drawing
Applications:
- HVAC Systems: Ensuring proper flow in heating, ventilation, and air conditioning systems.
- Fire Sprinkler Systems: Detecting when water flows due to sprinkler activation, triggering alarms.
- Industrial Processes: Monitoring fluid flow in pipelines and machinery to ensure operational efficiency.
- Cooling Systems: Protecting systems from overheating by ensuring cooling fluids are circulating.
The working principle of a flow switch is based on detecting the presence or absence of flow in a system and responding to that detection by activating or deactivating an associated device or system. This ensures that equipment operates safely and efficiently based on the actual flow conditions.
