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)
