Abstract: A device for measuring the level of a material (e.g., a liquid) in a tank is disclosed. An example device includes a non-buoyant flexible member and a plurality of sensor nodes distributed along the length of the flexible member. The sensor nodes are configured to indicate a change in orientation. A buoyant float provides a generally U-shape configuration for the flexible member, and causes an increasing number of the sensing nodes to depart from a substantially vertical orientation as the level of the material rises within the storage tank. A monitor is configured to monitor a signal indicating the change in orientation of the sensor nodes. As such, the device may be implemented to conveniently and accurately measure the liquid level in the tank.
