👉 A stalagmometer is a device used to measure the amount of water in a cave or underground chamber. It consists of two concentric cylindrical tubes, one at each end, and a small hole through which water flows from one tube into the other. As the water flows down the tubes, it creates a wave-like pattern that can be recorded by an analog or digital display. The stalagmometer is commonly used in geological surveys for measuring the amount of water in caves and underground chambers.
