Endurance activities, such as mountain biking, running, hiking, and military operations require proper and continuous hydration. Hydration systems traditionally used for outdoor activities require manual monitoring of water levels, either by gauging a pouch’s weight change, inspecting the bladder, or using commercially available flowmeters. Lack of accurate information can lead to underestimation of remaining water and potentially dangerous situations.

The Intelligent Hydration System is a fluid level sensor that enables easy-to-use bladder monitoring and can be integrated with most commercial hydration backpacks. The technology consists of two sensors connected to a small circuit that can be attached to either side of any pre-existing reservoir. A light-emitting diode display communicates the bladder’s fluid level to the user. The kit provides an accurate reading of the fluid content, irrespective of shaking and movement.
