How does adding a second probe improve the single probe electro-mechanical liquid level control?

Adding a second probe enhances the single probe electro-mechanical liquid level control by creating a differential for water usage. This differential allows for more accurate monitoring and control of the liquid level within the system. With two probes, the system can determine the difference between the high and low water levels more effectively, which helps in managing the fill cycles more efficiently.

This two-probe setup leads to better responsiveness when managing water levels—ensuring that the system can maintain a desired level without overfilling or running dry. Utilizing two probes allows for more precise control and helps prevent potential damage or inefficiencies that could arise from inaccurate measurements associated with a single probe system. This is particularly valuable in keeping the water levels stable during varying usage conditions, resulting in better safety and operational reliability.
