Under full load conditions, how much time should the solenoid be open when feeding makeup liquid to another vessel?

Under full load conditions, the solenoid should be open for 80% or more of the time to effectively feed makeup liquid to another vessel. This requirement arises from the need to maintain proper liquid levels and ensure that the system remains balanced during operation.

By keeping the solenoid open for an extended period, the makeup flow can continuously compensate for losses due to evaporation or other processes, thereby maintaining optimal operating conditions. If the solenoid were open for a shorter duration, such as 20%, 40%, or 60%, the system may experience drops in liquid levels, potentially leading to issues such as overheating, reduced efficiency, or even equipment malfunction.

Thus, maintaining an 80% or greater opening time for the solenoid ensures a reliable supply of makeup liquid, promotes stability within the system, and supports uninterrupted operation under full load conditions.
