Abstract
A system and methods for automatically adjusting pump operating parameters for at least one pump to accommodate solids encountered during a pumping operation. The output signal of a level sensor may be monitored so as to detect and account for variations therein. The power draw of the pump may also be monitored so as to detect and account for the presence of solids.
