Gravity: Water Flow Sensor

SKU: SEN0550

This Gravity: Water Flow Sensor is designed based on the electromagnetic principle. It adopts o-ring rubber seal and uses silicone sealant at the outlet end to ensure good waterproofness. Also, it embraces high anti-electromagnetic interference and anti-vibration capabilities, offering reliable performance and long service life. <br/> The sensor can be used with microcontrollers like Arduino UNO to measure the flow of liquids with high concentration and low mucosity like water, diesel, engine oil, milk, paint, detergent, honey, etc. (no impurity in liquid)
