The sensor has a standard 1/2″ coupling (21 mm) on both sides and is therefore easy to connect to, for example, a gardena garden system.(check the images for an example, gardena coupling is not supplied with this product!)

The output of the sensor gives 5 pulses per second with a duty cycle of approximately 50% for each liter of fluid passing through per minute: Q [L/min] = f_pulse [Hz]/5.

Specifications:

Voltage range: 5-15V
Pulse frequency per L/min: 5Hz
Measuring range: 1-30L/min (with an accuracy of +-10%)
Maximum water pressure: 1.75MPa
Working temperature: -25-80^oC
Duty cycle pulse: 50% +-10%
Voltage pulse (with 5V as input voltage): 4.7V

Pinout:

Red: Vcc/plus (5-15V)
Black: GND/min
Yellow: Signal

Example with a similar sensor. Adjust the next piece of code on line 17:

float calibrationFactor = 4.5;

To:

float calibrationFactor = 5;

Note: The liquid can only run in one direction, this is indicated by an arrow!
