{"product_id":"gravity-liquid-flow-sensor-g12","title":"Gravity: Liquid Flow Sensor (G1\/2)","description":"\u003cp\u003eThis DFRobot Gravity Liquid Flow Sensor is based on the electromagnetic principle. It adopts an O-ring rubber seal and uses silicone sealant at the outlet end to ensure good waterproofing. It embraces high anti-electromagnetic interference and anti-vibration capabilities, offering reliable performance and long service life.\u003c\/p\u003e\n\u003cp\u003eThe sensor can be used with microcontrollers like the Arduino UNO to measure the flow of liquids with high concentration and low viscosity like water, diesel, engine oil, milk, paint, detergent, honey and more (no impurity in liquid).\u003c\/p\u003e\n\u003cp\u003eThis version uses a \u003cstrong\u003eG1\/2 pipe diameter\u003c\/strong\u003e.
