Water Flow Meter Sensor With Hall Effect Pulse Output For DIY Cooling Solar Irrigation And Fluid Monitoring Setups Half Inch NPT Thread Measures 1 To 30 Liters Per Minute About 450 Pulses Per Liter Durable Dry Sensor Design

Single unit water flow meter with Hall effect output for DIY
✔️ 1/2" NPT inline thread, 1-30 L/min, 450 pulses/L, 5-24V

Inline water flow sensor sits in-line with your piping and uses a magnetized pinwheel and Hall effect sensor on the housing to count rotations. It's handy for DIY cooling loops, solar heaters, irrigation, and basic fluid monitoring setups.

✅ 1-30 L/min flow range
✅ 450 pulses per liter for easy counting
✅ 3-wire: red (5-24V), black (ground), yellow (pulse)
✅ 1/2" NPT inline thread
✅ Dry sensor design keeps electronics safe
