Potable Water Flow Switch, G1/4'', NO

High-sensitivity potable water flow switch features a G1/4'' female threaded connection for easy installation. With a minimum activation flow rate of ≥1L/min and a shut-off flow range of 0.8–1L/min, it responds in just 0.2 seconds to rapidly detect water flow changes, enabling precise start/stop control. The switch offers a normally open (NO) design, compatible with electrical environments of DC < 100V and AC < 110V at 0.5A, with a power rating of 10W. Suitable for water temperatures of 5–60°C and humidity < 85%, it is widely used in water purifiers, water dispensers, and water treatment equipment.

Feature

• Standard Interface: Features a G1/4'' female threaded connection compatible with common water purification equipment and piping systems.
• Stable Electrical Performance: The SUCH drinking water switch supports DC <100V or AC <110V at 0.5A operating conditions, ensuring reliable switching performance.
• Robust Construction: Withstands 20N × 10s axial and vertical tensile testing without damage. Features 0.8MPa pressure resistance and meets 50cm drop test standards, delivering excellent impact resistance.

Wiring Diagram

When dealing with slightly higher currents, such as those from load pumps, alarms, contactors, and solenoid valves, a small relay must be used in conjunction.

Relay Wiring Diagram

Note: When the power exceeds the relay's load capacity, additional contactors must be added. Refer to the wiring diagram above.
