👉 A salinometer is a device used to measure water quality. It consists of two parallel metal plates, one with a narrow opening and the other with an open end. The water enters the narrow opening at the bottom of the plate, which creates a pressure difference between the two plates. When the water flows through the plate, it exerts a force on the other plate, causing it to close or open. This force is proportional to the amount of salt present in the water and can be used
