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.

Abstract
Systems and methods to determine the apparent density of a fluid being displaced by a pump. The apparent density may be determined by comparing an expected torque of the pump to an actual torque of the pump. The apparent density can also be used to detect irregular operating conditions.

8. A pump monitor comprising:
-
an interface configured to receive sensor data from a voltage sensor, current sensor, and temperature sensor connected to a motor of a pump; a processor; and a non-transitory memory connected to the processor, storing instructions thereon that, when executed by the processor, cause the processor to; determine an expected torque value for the pump using the sensor data; determine an actual torque value for the pump using the sensor data; use the expected torque value and the actual torque value to determine an apparent density of the fluid; use the apparent density to detect an irregular operating condition; and generate an alert if an irregular operating condition is detected. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An ebullating pump system comprising:
-
an ebullating pump having a motor; sensors connected to the motor that measure the voltage, current, and temperature of the motor; and a pump monitor that; receives sensor data from the sensor; stores relationship data in a memory that relates the speed of the pump to torque; utilizes a processor to determine an expected torque using the sensor data and the relationship data, to determine an actual torque for the pump by using the sensor data, and to determine an apparent density of the fluid based on the expected torque and actual torque; uses the apparent density to detect an irregular operating condition; and generates an alert if an irregular operating condition is detected. - View Dependent Claims (16, 17, 18, 19, 20)
