How It Works
- The weight of the inner container drops during to evaporation and plant demand. The container then floats, breaking the valve seal and allowing fluid from the reservoir to the inner container as the valve opens.
- The inner container increases in weight due to fluid intake, overcoming the buoyancy force of the reservoir and closing the valve seal, which stops the fluid flow.
