Magnetic Depth Meter

In this instructable we’re going to show you how to build you own magnetic water depth meter. Our depth meter works with the concept of communicating vessels. The sensors are attached to a vessel that is connected to the water body that you want to measure, in this case a measuring beker. The vessel with the sensors will have a floating magnet in it, which will float with the water level, allowing you to measure it quite precisely. With the following steps we hope that it will be clear for you how to make this sensor.”
