Abstract

There is provided a method that includes, (a) monitoring a pressure on a fluid being conveyed through an intake tube into a chamber by a pump, (b) determining a deviation of the pressure from a predefined value, (c) determining a blockage of the intake tube based on the deviation, and (d) determining an amount of an adjustment of a parameter of the pump to compensate for the blockage.

Claims (19)

1. A method comprising:

monitoring a pressure on a fluid being conveyed through an intake tube into a chamber by a pump;

determining a deviation of said pressure from a predefined value;

determining a blockage of said intake tube based on said deviation; and

determining an amount of an adjustment of a parameter of said pump to compensate for said blockage.

2. The method of claim 1 , further comprising, sending a signal to adjust said parameter of said pump by said amount.

3. A computer-readable medium, comprising:

instructions for controlling a computer to:

monitor a pressure on a fluid being conveyed through an intake tube into a chamber by a pump;

determine a deviation of said pressure from a predefined value;

determine a blockage of said intake tube based on said deviation; and

determine an amount of an adjustment of a parameter of said pump to compensate for said blockage.

4. The computer-readable medium of claim 3 , wherein said instructions further control said computer to output a signal to adjust said parameter of said pump by said amount.

5. A system comprising a processor that:

monitors a pressure on a fluid being conveyed through an intake tube into a chamber by a pump;

determines a deviation of said pressure from a predefined value;

determines a blockage of said intake tube based on said deviation; and

determines an amount of an adjustment of a parameter of said pump to compensate for said blockage.

6. The system of claim 5 , wherein said processor also outputs a signal to adjust said parameter of said pump by said amount.
