Electronic Flow Switch, PNP/ NPN/ Relay

Electronic flow switches primarily detect fluid flow status through sensing elements, converting the signal into an electrical output. Compared to traditional mechanical water flow switches, they offer faster response times, higher repeatability accuracy, and longer contact lifespans. Mechanical switches rely on spring or reed switch mechanisms, which may experience wear or sticking over extended use. Electronic designs provide greater stability and are well-suited for automated control systems. Translated with DeepL.com (free version)

• When installing electronic flow switches, ensure the flow direction aligns with the product's arrow indicator. Avoid installation in areas with strong magnetic fields or high vibration to prevent sensitivity issues.
• Certain models require vertical or horizontal installation; follow the instructions accordingly.
• Keep the pipe interior clean to prevent debris from jamming internal components. When wiring, verify voltage and current parameters match to avoid exceeding the rated load.
• After installation, conduct a water flow test to check for leaks or signal abnormalities, ensuring stable system operation.

When an electronic flow switch experiences frequent false triggering or fails to activate, follow these steps: First, verify that water pressure and flow rate meet the activation thresholds. Next, check for a stable power supply voltage. Then, inspect wiring for loose connections or moisture exposure. In high-humidity environments, test whether insulation resistance has decreased.
