The liquid flow sensor is used to read the rotation of water or liquids with a capacity of 1 to 25 L per minute. It detects even a small flow of liquid. Suitable for water heaters and automatic water dispensers mounted on 1/2 inch piping. It can be used in various DIY projects. An example project for an Arduino flow meter - Click HERE.
