Adafruit Liquid Flow Meter - Plastic 1/2" NPS Threaded

Measure liquid flow for your solar, computer cooling, or gardening project using this basic flow meter. This sensor integrates seamlessly with your water line using a pinwheel sensor to monitor liquid movement. A built-in magnet and hall effect magnetic sensor ensure accurate readings while keeping the system safe and dry.

The sensor is equipped with three wires: red for 5-24VDC power, black for ground, and yellow for hall effect pulse output. Count the output pulses to track fluid movement, with each pulse corresponding to approximately 2.25 milliliters.

Although not designed as a precision instrument, it is ideal for basic measurement tasks. Calibration is recommended for precision beyond 10%. Enhance your projects with an example Arduino sketch that calculates fluid quantity in liters, displaying it on an LCD or serial monitor.
