Pump system with dynamic level control

A pump comprising:

• an inlet port;
• a discharge port;
• a fluid sensor configured to detect a fluid;
• and
• a controller configured to:
• activate the pump in response to the fluid sensor detecting the fluid,
• after activating the pump, initiate a shutoff delay timer having a shutoff delay time when the fluid sensor no longer detects the fluid,
• increase the shutoff delay time if the fluid sensor detects the fluid before the shutoff delay time has elapsed, and
• maintain the shutoff delay time if the fluid sensor does not detect the fluid before the shutoff delay time has elapsed.

A method of controlling a level of fluid with a pump having a motor, an inlet port, a discharge port, and a fluid sensor configured to detect a fluid, the method comprising:

• activating the pump in response to the fluid sensor detecting the fluid;
• initiating a shutoff delay timer when the fluid sensor no longer detects the fluid, the shutoff delay timer having a shutoff delay time;
• increasing the shutoff delay time if the fluid sensor detects the fluid before the shutoff delay time has elapsed;
• and
• maintaining the shutoff delay time if the fluid sensor does not detect the fluid before the shutoff delay time has elapsed.
