Áramlásmérő YF-S201 1/2 "1-30l / perc Arduino-hoz

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).
