1. A method for determining an apparent density of a fluid being displaced by a pump having a motor comprising:

  • receiving, at a computer, sensor data indicative of the voltage, current, and temperature of the motor;

    determining an expected torque value for the pump using the sensor data;

    determining an actual torque for the pump using the sensor data;

    using the expected torque and actual torque to determine an apparent density of the fluid;

    using the apparent density to detect an irregular operating condition; and

    generating an alert if an irregular operating condition is detected.
