With this sensor you can easily measure the flow of liquids (water).

The sensor has a standard 1/2" coupling (21mm) on both sides and is therefore easy to connect to, for example, a Gardena garden system (see images)(Gardena coupling not included). 

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] = fpulse [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: -25-80oC
  • 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!

Mooie sensor, werkt prima. Ik gebruik 'm als flowmeter voor de waterkoeling van mijn frees-spindel. Wat mij bij het testen opviel is dat luchtbellen de werking negatief beïnvloeden. Ik heb de sensor aan de retourleiding van de waterkoeling gemonteerd en bovenin de watertank gemonteerd. Bij horizontale montage komt er lucht bij het bovenste deel van het 'fannetje' en dan doet de sensor het niet altijd even goed. Bij vertikale montage werkt alles prima.
