The DN15 G1/2" Water/Air Flow Switch Sensor is a compact inline fitting that detects whether water or air is actually moving through a pipe. When flow starts or stops, the switch changes state and can signal a pump, controller, or alarm. With its standard G1/2" (DN15) threaded connection, it fits easily into common small-bore lines, making it a practical choice for home gardens, farms, hydroponic setups, and DIY automation projects.
Key features
- Standard G1/2" (DN15) threaded connection for easy inline installation.
- Works with both water and air flow detection.
- Compact body that fits in tight spaces and small piping runs.
- Switches state on flow, so it can drive a pump, controller, or alarm.
- Simple to wire and integrate into existing systems.
Typical uses
- Protecting irrigation or transfer pumps from running dry when there is no flow.
- Confirming flow in drip and small irrigation lines.
- Monitoring water or air movement in hydroponic and aquarium systems.
- Triggering signals in home and project-level automation builds.
How to choose / tips
- Check that your pipe matches the G1/2" (DN15) thread before ordering.
- Install it with the flow direction the right way and seal threads with tape.
- Match the switch to your controller's input so the signal is read correctly.
- Keep the line clean to avoid debris affecting the sensor.
