In a mercury system, what happens when the tank level reaches 10%?

In a mercury system, when the tank level reaches 10%, the appropriate response is that the pumps turn off. This action helps to prevent damage to the system and ensures safe operation. When the tank level is low, continuing to pump could lead to the pump running dry, which could cause overheating or mechanical failure.

Monitoring the tank level is crucial in fluid systems, particularly when dealing with hazardous substances like mercury, to avoid accidents and maintain operational safety. Other responses, such as sounding alarms or activating pumps, would typically occur at different levels to indicate a need for attention or action, highlighting the importance of keeping the system’s operations within predefined safety parameters.
