  • Patent number: 10975682
    Abstract: Systems and methods for determining the resistance of a power cable of an ESP. The nameplate resistance of the motor is determined prior to installation of the ESP in the well, and the temperature is determined for a point in the well at which the motor will be positioned. The downhole temperature and nameplate resistance are used to calculate an initial downhole resistance of the motor. After the ESP is installed, but before operation of the ESP is initiated, the electric drive for the system generates a measurement voltage and applies the measurement voltage to the power cable and motor. The corresponding current is then measured and is used to calculate the resistance of the string (the combined power cable and motor). The calculated initial downhole resistance of the motor is then subtracted from the resistance of the string to obtain the resistance of the power cable.

  • Patent number: 9347847
    Abstract: A pressure transmitter includes at least one impulse line for coupling a fluid pipe or tank to a pressure sensor that measures a process pressure of a process fluid, a temperature sensor measuring an ambient temperature, and a processor accessing baseline data for the process pressure and ambient temperature. The processor implements an automatic impulse line plugging diagnostic (ILPD) algorithm stored in memory. The processor runs the ILPD algorithm implementing utilizing process measurements including a process pressure from the pressure sensor and an ambient temperature from the temperature sensor, comparing a magnitude of the process pressure to a baseline pressure predicted from the baseline data corresponding to the ambient temperature, and uses results of the comparing to determine whether the impulse line is plugged. The comparing can involve comparing a process pressure change to a baseline pressure change predicted corresponding to an ambient temperature change.

  • Patent number: 9212664
    Abstract: A control circuit for controlling the rotational speed of a fan may include a memory element to store operating data corresponding to an operational profile of the fan defined by RPM (revolutions per minute) versus temperature, with the operating data comprising a respective temperature value and a respective RPM value for each respective operating point representing a change in slope of a function that corresponds to the operational profile of the fan. A processing unit may receive a present temperature value, retrieve the operating data from the storage unit, and identify a pair of consecutive operating points corresponding to the present temperature. The processing unit may calculate a desired RPM value corresponding to the present temperature value by performing linear interpolation between the pair of consecutive operating points, and provide the desired RPM value to a closed-loop fan controller to control the fan according to the desired RPM value.

  • Patent number: 8965725
    Abstract: In order to mitigate the negative effects of a change in atmospheric pressure, an improved capacitance diaphragm gauge (CDG) sensor incorporates an independent ambient atmospheric pressure sensor near the CDG sensor body. The ambient atmospheric sensor is located outside the CDG sensor body to sense the ambient atmospheric pressure surrounding the CDG sensor body. The ambient atmospheric sensor provides an output that represents the ambient atmospheric pressure. A sensor output processing circuit receives the output of the ambient atmospheric sensor as well as the output of the CDG sensor. The processing circuit utilizes the output from the ambient atmospheric pressure sensor to fine tune the CDG measurement of pressure by executing an in situ, real time, automatic calibration adjustment of the CDG.
