Examples

• The building's water system uses hydrostats to maintain consistent pressure throughout the pipes.
• Modern hydrostats can automatically shut off water supply when tanks reach maximum capacity.
• Engineers installed new hydrostats in the irrigation system to prevent overflow.
• Fish use hydrostats and other sensory organs to navigate in dark water.
• The hydrostat in the boiler prevents dangerous pressure buildup.
