    Abstract: Aspects and embodiments disclosed herein indicate a correlation exists between a specific gravity of combustible fuel and the occurrence of low-speed pre-ignition (LSPI) within engines. Thus techniques are disclosed herein for online measurement of the specific gravity of fuel within an engine, and allow for preventative measures to be executed to minimize or otherwise mitigate the incidence of LSPI when the calculated specific gravity of the fuel exceeds a predefined threshold. In an embodiment, the preventative measures may include, for example, altering or otherwise adjusting an engine map such that an injection timing scheme injects less poor-quality fuel into engine cylinders, thus advantageously preventing the engine from operating at full-power when conditions for LSPI are present.

  • Patent number: 8707779
    Abstract: A system for measuring and monitoring the internal liquid within a three phase separator allows a user to accurately and reliably calculate the volumetric flow rate of the liquids exiting the three phase separator. For each liquid inside of the three phase separator, a differential pressure device is attached to where the extension fitting enters its respective liquid. Once a dump valve is actuated, the extension fitting guides its respective liquid out of the three phase separator, and the differential pressure device creates a differential pressure within the respective liquid. A sensor reads the differential pressure through a pair of sensing lines. The sensor relays the differential pressure reading to an RTU flow computer that calculates the volumetric flow rate of the liquid exiting the three phase separator. The calculation is then sent to a SCADA system, which allows the user to observe the volumetric flow rate in real time.

A first characteristic of the plurality of characteristics is determinable from data generated by the sensing device. A second characteristic of the plurality of characteristics is determinable from data generated by the sheltered device. In one exemplary embodiment, the first characteristic is a gas fraction, and the sensing device is a plurality of pressure sensors. In another exemplary embodiment, the second characteristic is a phase fraction, and the sheltered device is a plurality of electrical impedance spectroscopy (EIS) electrodes.

  • Patent number: 8230735
    Abstract: A flow rate of a fluid flowing in a tubing is determined using a flow meter. The flow meter measures a value related to the flow rate. The tubing has a valve for controlling the fluid flowing through the flow meter. The method of determination of the flow rate includes closing the valve and measuring a first zero flow rate value at a first time and a second zero flow rate value at a second time, estimating an error of the value measurement based on the first and second zero flow rate values, opening the valve and measuring value of the flowing fluid, applying an error correction to the measured value of the flowing fluid, and calculating a corrected flow rate based on the corrected value of flowing fluid.

  • Publication number: 20120094261
    Abstract: A flow meter for a container, for monitoring the dehydration of a patient, has a sensor unit for detecting a flow through the flow meter and a control unit for recording an amount of liquid passing through during a time interval. The flow meter is an adapter for connection to a bottle or a beaker. A patient receives a warning if he should take in liquid. A base station serves for bidirectional transmission of measurement data to an external apparatus, more particularly a telemedical center.

  • Patent number: 8061219
    Abstract: A flow rate device for measuring the flow rate of a fluid flowing through a wellbore is disclosed. The flow rate device includes a differential pressure conduit, a flow restrictor insert and a differential pressure measurement device. The differential pressure conduit is locatable in the wellbore, defines an internal bore, and is adapted to include a restriction having a cross-sectional area to increase the velocity of fluid flowing through the differential pressure conduit to create a differential pressure. The differential pressure conduit defining first and second pressure measuring stations axially spaced along the differential pressure conduit. The flow restrictor insert is located in the restriction to reduce the cross-sectional area of the restriction. The flow restrictor insert defines an internal bore having a cross-sectional area less than the cross-sectional area of the restriction. The flow restrictor insert also has a pressure measuring port aligned with the second pressure measuring station.
