What is the primary function of a float chamber in a surge tank?

The primary function of a float chamber in a surge tank is to indicate the minimum water level. The float chamber utilizes a floating device that rises and falls with the water level within the surge tank. This mechanism allows for continuous monitoring of the water level, providing a visual or mechanical indication when the water level drops to a predetermined minimum point.

Maintaining an adequate water level is crucial for the functionality of the surge tank, which serves to absorb fluctuations in system pressure and prevent issues such as cavitation in pumps or system failures due to insufficient flow. Therefore, having an effective float chamber that signals when the water level is critically low plays a vital role in system safety and operational efficiency.
