With this sensor you can easily measure the flow of liquids (water).
The sensor has a 7mm coupling on both sides and is therefore easy to connect to a 6mm hose.
The output of the sensor gives 98 pulses per second with a duty cycle of approximately 50% for each liter of fluid passing through per minute: Q [L/min] = fpulse [Hz]/98.
Example with a similar sensor. Adjust the next piece of code on line 17:
float calibrationFactor = 4.5;
float calibrationFactor = 98;
Note: The liquid can only run in one direction, this is indicated by an arrow!
