Water Paddle Flow Switch Key benefits Protects equipment by detecting water flow and activating/deactivating circuits when flow changes, helping prevent dryrun, overheating, or inefficient operation. Durable, simple mechanism suited for both indoor and outdoor installations for longterm, lowmaintenance use. Compact, lightweight design for easy integration into existing plumbing and HVAC systems. Main features Compatibility: Designed for heat pump water heaters and air conditioning systems; also suitable for pool equipment, central air conditioners, coffee machines, and similar waterflow applications. Adjustable flow sensitivity: Detects flow from 1 L/min and up, allowing use across a range of lowflow to higherflow situations. Pressure tolerance: Rated to withstand a maximum pressure of 1 MPa or higher. Paddlebased mechanism: Precisionengineered nylon paddle responds quickly to water movement to trigger the switch reliably. Temperature resistance: Operates across a wide temperature range from 10°C to 100°C. Electrical ratings: Working voltage 100 V with a current rating of 0.5 A, providing stable electrical performance under continuous use. Construction: Lightweight, spacesaving form factor for straightforward installation without significant system rework. Typical applications Heat pump water heater protection: Ensures the heater or circulation pump runs only when sufficient water flow is present, preventing damage from lowflow conditions. HVAC and central air conditioning: Monitors chilled or condenser water circuits to confirm proper circulation and trigger system controls or alarms if flow falls below setpoint. Small equipment and appliances: Suitable for use in pool circulation lines or coffee machines where reliable lowflow detection and compact installation are required. What it solves Prevents equipment damage caused by insufficient flow. Provides a reliable, mechanical flowsensing solution that requires minimal calibration and maintenance. Fits into tight spaces and standard systems thanks to compact dimensions and straightforward electrical connection. Specifications (as provided) Flow sensitivity: adjustable from 1 L/min Maximum pressure tolerance: 1 MPa or higher Paddle material: nylon Operating temperature: 10°C to 100°C Working voltage: 100 V Current rating: 0.5 A Installation notes Mount in the flow path so the nylon paddle can move with water movement. Verify voltage and current compatibility with your system controls before wiring. Suitable for indoor and outdoor use when installed according to local codes and environmental protections.
