Flow meter YF-S201 1/2 "1-30l / min for Arduino

The water flow meter 1–30L / min allows to measure the amount of flowing liquid by means of a Hall probe. At the output, the frequency changes depending on the flow rate, the higher the flow rate, the higher the frequency. Can be used up to a maximum liquid temperature of 80 ° C.


Technical parameters:

- thread: G 1/2 "
- measured flow: 1 ~ 30 l / min
- max. working pressure: 1.75MPa
- output: 5V TTL
- max. working temperature: up to 80 ° C
- operating humidity: 35% ~ 90% RH (without icing)
- power supply: 5-15VDC
- max consumption: 15mA
- pulse characteristics: 450 pulses / liter or f (Hz) = 7.5 * flow (l / min)
- measurement accuracy: 2%
- cable length: ~ 15cm
- dimensions: 65 × 40mm
- connection: red: + 5V, black: GND, yellow: OUT (output to digital pin arduina)
