💡 What is a water flow sensor switch and how does Hall-effect sensing benefit DIY plumbing?

In short, it's a handy device that detects liquid flow and translates it into pulses for a controller, enabling precise monitoring and control in home systems.

• Great for monitoring heater inlet flow and preventing dry running
• Non-contact sensing protects both the liquid and electronics
• Easily retrofits to standard G3/4 BSPT fittings
• Works with 5-15 V DC controller inputs
