The FPR paddle flow switch for liquids is a precision mechanical device designed to monitor and control liquid flow in industrial piping systems. It provides dependable flow detection for applications such as cooling circuits, industrial refrigeration systems, HVAC installations, and process automation lines.
In fluid handling environments, maintaining consistent flow is critical to prevent equipment damage, overheating, or system failure. The paddle flow switch ensures immediate detection of reduced or interrupted liquid flow, enabling automated shutdowns or alarms to protect pumps, compressors, and heat exchangers. Built with robust industrial materials and a compact design, the device offers reliable performance even in demanding industrial environments.
Key Features
- Mechanical paddle-based liquid flow detection
- Durable brass paddle and brass pipe fitting construction
- IP65 protection for industrial environments
- Wide operating temperature range for liquids and ambient conditions
- Adjustable switching set point for flexible process control
- Compatible with water, coolant, glycol, and similar liquids
- Reliable NO contact switching for automation systems
These features make the paddle flow switch suitable for industrial automation, HVAC installations, refrigeration circuits, and liquid processing systems.
Design & Functionality
The paddle flow switch operates using a mechanical paddle inserted into the liquid pipeline. As liquid flows through the pipe, the paddle moves proportionally with the flow rate. When the flow exceeds the predefined set point, the internal magnetic mechanism activates the electrical contact.
If the liquid flow drops below the threshold or stops completely, the switch returns to its original position and triggers a signal. This mechanism provides a simple yet highly reliable solution for detecting flow conditions without complex electronics.
Total Crossed Beams
The device is designed to ensure consistent switching accuracy across the flow path. The paddle interacts directly with the moving liquid, providing precise mechanical feedback to the internal magnetic switching system.
Beam Pitch Options
Multiple set-point configurations allow the switch to operate across different pipe sizes and flow conditions. Adjustable switching points enable system engineers to calibrate the device based on application requirements and pipeline characteristics.
Intrinsic Synchronism
The internal magnet and contact assembly provide synchronized switching performance, ensuring stable signal transmission during changing flow conditions. This design minimizes false triggering and improves system safety in critical industrial processes.
Operational Advantages
The paddle flow switch provides several operational benefits for industrial fluid control:
- Protects pumps and compressors from dry-running
- Ensures safe operation of refrigeration and cooling circuits
- Improves process reliability in fluid systems
- Requires minimal maintenance due to simple mechanical design
- Supports continuous monitoring in harsh industrial environments
With its durable construction, reliable switching performance, and flexible installation options, the paddle flow switch is a trusted solution for liquid flow monitoring in industrial manufacturing systems.
