Transparent Water Flow Sensor (Sea) YF-S201C Flowmeter G1/2 1-30L/min 5-15V

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 (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 = fpulse /5.

Voltage range: 5-15V

Pulse frequency per L/min: 5Hz

Measuring range: 1-30L/min (with an accuracy of +-10%)

Maximum water pressure: 17.5bar

Working temperature: -25-80°C

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

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