1/4" NPT Water Flow Switch – Liquid Flow Sensor for Dispensers, Purifiers, and PE Tubing Systems
1/4" NPT Water Flow Switch – Liquid Flow Sensor for Dispensers, Purifiers, and PE Tubing Systems
This 1/4" NPT Water Flow Switch is a compact, sensitive flow sensor designed to detect the presence or absence of water or liquid in PE tubing systems. Ideal for water purifiers, dispensers, coffee machines, and other fluid control applications, it automatically triggers a signal when flow is detected. With a built-in magnetic switch (reed switch) and durable plastic housing, it ensures long-lasting performance in residential or commercial liquid systems.
🔑 Key Features:
- 💧 1/4" NPT Thread – Compatible with standard PE tube water systems
- 🔁 Magnetic Reed Switch Inside – Opens/closes circuit based on flow presence
- 🧊 Durable Plastic Body – Lightweight, corrosion-resistant housing
- ⚡ Low Power Consumption – Works with control systems, microcontrollers, solenoids
- 🔧 Easy Installation – Inline fitting with threaded ends for tight and leak-proof connection
