Paddle Type Water Flow Sensor with Accurate Flow Detection and Automatic Pump Protection for Plumbing

Water Paddle Flow Sensor F61KB11C, Gray Key benefits Accurate flow and level detection for reliable system control. Prevents dry running and unmonitored flow conditions by providing a clear electrical signal when liquid moves past the paddle. Simple integration with plumbing and DIY control systems. Designed for use as a flow switch or water level control sensor in common liquid handling setups. Operates across a wide temperature and pressure range to suit many applications. Rated for liquid temperature 0 to 121 and maximum pressure 1MPa. What this product does Detects flow or presence of liquid using a paddle style mechanism and outputs a switch signal for pump control, alarms, or automation systems. Functions as a flow switch and water level control sensor in pipes, tanks, and lines. Important attributes Model: F61KB11C Color: gray Function: paddle flow sensor and water level control flow switch for liquids Compatibility: designed for plumbing and DIY supplies applications and for integration into pump and control circuits Performance: liquid temperature range 0 to 121; greatest pressure 1MPa Why customers need this sensor Protects pumps and equipment by enabling automatic control when flow starts or stops. Helps maintain system reliability with a straightforward mechanical sensing method that is easy to monitor electrically. Fits common plumbing projects and DIY installations where quick feedback on liquid movement is required. Practical installation notes Mount the sensor in the flow path or tank area where paddle movement will reliably register liquid movement. Connect the switch output to pump starters, relays, or control inputs according to system voltage and wiring requirements. Verify temperature and pressure ratings match system conditions before installation. Use scenarios 1) Pump protection in a residential water system: Install in the pump discharge or line to stop the pump if flow stops and prevent dry running. 2) Tank level control for a small process or irrigation system: Use the sensor as a level switch to detect liquid movement into or out of a tank and trigger fill or stop actions. 3) Flow monitoring for cooling loops or recirculation systems: Detect when circulation starts to confirm pump operation and provide a fault signal if flow is not present. What makes this product stand out Paddle based detection offers clear mechanical action that translates to a dependable electrical signal for control logic. Compact form and plumbing compatibility make it suitable for retrofit and installations in a wide range of small to medium systems. Clear specification of model, temperature range, and pressure rating helps ensure correct selection for common applications. Technical summary Model number: F61KB11C Color: gray Liquid temperature: 0 to 121 Greatest pressure: 1MPa Function: water paddle flow sensor, flow switch, water level control liquid sensor This sensor is intended for plumbing and DIY control applications where simple, reliable detection of liquid flow or level is required.
