The method includes providing an electrochemical impedance sensor at a fixed location in the pipeline for continuously measuring the impedance value of the flowing production fluid at such location. A sample of the production fluid is obtained from the pipeline to determine the watercut value of the sample. From such watercut values from the sample, a correlation formula is determined of the watercut value of the sample with the measured impedance value at the fixed location. Subsequently the continuously measured impedance values are inputted into the correlation formula to continuously calculate the watercut value of the flowing production fluid to thereby continuously determine the watercut of the flowing production fluid with the impedance sensor.

  • Patent number: 9522395
    Abstract: A pipette is described which includes a piston for aspirating liquid into and dispensing out of a container in the pipette. The pipette is provided with at least one tracking element which is able to count the magnitude of some variable or variables relating to the amount of use of the pipette, at least one operating device for creating a limit magnitude for each variable, and for giving information when the limit value is exceeded. Thus, the user may, for instance, be warned when he may be exposed to high workload stress possibly causing injuries.

  • Patent number: 9513149
    Abstract: A Coriolis flowmeter has a driver that oscillates a conduit, a first sensor configured to generate a first sensor signal indicative of movement of the conduit at a first location, and a second sensor configured to generate a second sensor signal indicative of movement of the conduit at a second location. The first and second locations are arranged so a phase difference between the first and second signals when the conduit is oscillated by the driver is related to a mass flow rate of the fluid through the flowmeter. A digital signal processor includes a plurality of detectors tuned to a set of different frequencies. The detectors are configured to analyze the first sensor signal in parallel and generate an output indicative of how closely an actual frequency of the first sensor signal matches the frequency to which the respective detector is tuned.

  • Patent number: 9472084
    Abstract: Monitoring circuitry monitors a computing device for configuration changes and performance changes. The monitoring circuitry also logs that data (CDD and PDD data) to a database. An analysis circuit analyzes the CDD and PDD data to determine whether an anomaly exists. If the analysis circuit determines that an anomaly exists, it generates an alarm to alert appropriate personnel to the anomaly.

    Abstract: Systems and methods for identifying a faulty sensor are provided. One system includes multiple sensors, each generating a first set of parameters based on detected measurands. The system also includes a fusion module for generating a second set of parameters by fusing the first sets of parameters, and a sensor fault module including multiple fault templates defining sensor faults, an estimation module for generating a third set of parameters based on the first and second sets of parameters, and an evaluation module. The evaluation module is configured to compare the third set of parameters and the fault templates, and determine a sensor fault based on the comparison. A method includes receiving a first set of parameters based on measurands from multiple sensors and a second set of parameters based on a measurand from a sensor, and determining a sensor fault based on the first and second set of parameters.

  • Patent number: 9243971
    Abstract: According to the present invention, there is provided a method of monitoring a fluid in a fluid carrying conduit comprising the steps of: monitoring a fluid characteristic at a first point and second point along the conduit substantially continuously; determining first and second quantities, being related to a differential with respect to time of the value of the fluid characteristic at the first and second points respectively; combining the first and second quantities to produce a two dimensional intensity function of time and a position variable and analyzing the magnitude of the intensity function to derive information relating to the fluid. The intensity function may represent a substantially continuous probability function, wherein its absolute value is related to the probability of a leak or theft having occurred in the conduit.

  • Patent number: 9183326
    Abstract: A method for computing or estimating fractional, multi-phase/multi-component flow through a porous medium employing a 3D digital representation of a porous medium and a computational fluid dynamics method to calculate flow rates, pressures, saturations, internal velocity vectors and other flow parameters is described. The method employs a unique method of introducing non-wetting and wetting fluids into the pores at the inlet face of the 3D digital representation of a porous medium and a novel process control application to achieve quasi-steady state flow at low inlet concentrations of non-wetting fluid. In addition, the method of the present invention reduces the time required to simulate to complete the fluid dynamic calculations. The resulting values of flow of non-wetting fluid, wetting fluid, saturation, and other parameters are used to generate plots of relative permeability imbibition and drainage curves. Computerized systems and programs for performing the method are also provided.

  • Patent number: 9134441
    Abstract: A cross-sectional area calculation section calculates a cross-sectional area of a subject as physical quantity with respect to a size of the subject, and an NEC calculation section calculates a noise equivalent count NEC as physical quantity for evaluating an image. The C-NEC calculation section calculates a noise equivalent count per unit area C-NEC as physical quantity for evaluating an image as per size of the subject in accordance with the cross-sectional area of the subject calculated in the cross-sectional area calculation section and the noise equivalent count NEC calculated in the NEC calculation section. Accordingly, the noise equivalent count per unit area C-NEC is calculated as noted above, whereby an index may be determined that is independent of the cross-sectional area of the subject in evaluating the image.
