Automatic ironpaddle flow switch and valve sensor that delivers accurate flow detection and reliable control for a wide range of liquid systems. Key benefits Accurate flow detection: Builtin automatic iron paddle provides consistent sensing of flow rate so equipment and processes respond only when liquid is present. Protects equipment and processes: Triggers pumps, valves, alarms, or control systems to prevent dry run, reduce wear, and avoid process interruptions. Easy to install and fit: Available in 1 inch, 3/4 inch, and 1/2 inch sizes to match common pipe connections and simplify retrofit or installations. Robust performance: Designed for continuous use between 0°C and 80°C and rated for system pressures up to 8Mpa. Reliable electrical switching: Handles resistive loads up to AC125V3.5V for stable, repeatable switching in control circuits. Features and specifications Sensing element: Automatic iron paddle for mechanical, flowdriven operation. Sensor type: Valve sensor, available in sizes 1 inch, 3/4 inch, and 1/2 inch. Operating temperature: 0°C to 80°C. Maximum pressure: Up to 8Mpa. Electrical load capacity: Resistive loads up to AC125V3.5V. Application compatibility: Suitable for a variety of liquid applications where the paddle material and operating limits meet process requirements. Typical applications Pump protection in water supply or circulation systems: Detect flow to prevent pumps from running dry and to automate pump staging. HVAC and chilledwater systems: Monitor loop flow to confirm pump operation and trigger interlocks or alarms during loss of flow. Industrial process lines: Provide simple, reliable flow status feedback for control panels, valves, and safety systems in liquidhandling processes. Why choose this switch Clear, mechanical detection method with an iron paddle that directly responds to flow rather than relying on indirect signals. Multiple size options for quick integration into existing pipework. Designed to operate across common temperature and pressure ranges found in industrial and commercial liquid systems. Straightforward electrical switching capacity for interfacing with control and protection circuits. Installation and use notes Select the size (1 inch, 3/4 inch, or 1/2 inch) that matches the system connection to ensure proper fit and reliable sensing. Confirm compatibility of the iron paddle with the specific liquid to avoid corrosion or wear issues in aggressive chemistries. Ensure system temperature and pressure stay within the specified ranges (0°C to 80°C, up to 8Mpa) for safe, reliable operation. Verify electrical requirements and wiring meet the resistive load specification (AC125V3.5V) when connecting to control equipment.
