• NPT Thread
• 1-30L/min
• The Water Flow Sensor is light, has a nimble outline, small, and is easy to install—the bearings used in the rotating part.
• There is an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.
• Installed by flow direction in the product, otherwise, there is no signal output.
• It is mainly used in water heaters, coffee machines, water purifiers, drinking fountains, beverage machines, campus smart card equipment, etc.
