  • Patent number: 11965767
    Abstract: A guided wave radar level gauge adapted for mounting on a nozzle of a tank, including an attachment collar with an opening configured to be aligned with the nozzle and to be secured by means of an annular clamping device, and a transmission line probe attached to an exterior end of a probe connector. The GWR level gauge further comprises an annular sealing gasket fitted in the collar opening, the annular sealing gasket having a central opening through which the central probe connector extends, and a distancing sleeve arranged around the exterior end of the probe connector and having a radially protruding collar portion, wherein processing circuitry is configured to detect an impedance change caused by tank content or condensate which has passed through the central opening of the sealing gasket and collected in an annular space immediately surrounding the radially protruding collar portion.

  • Patent number: 8894744
    Abstract: A system is provided for removing particulate matter from a particulate collection device utilized to collect particulate matter from a flue gas stream. The system includes a pressure vessel for storing a pressurized gaseous medium in an interior area defined by the pressure vessel. A first pressure sensor is in communication with the interior area and configured to measure pressure therein. A particulate collection device for collecting particulate matter from a flue gas stream includes a conduit in communication with the pressure vessel. A valve is disposed in the conduit and adapted to open to release a pulse of the pressurized gaseous medium from the pressure vessel into the particulate collection device. A control system is in communication with the valve and the first pressure sensor, and includes a controller configured to operate the valve based upon at least one pressure measurement received from the first pressure sensor.

  • Patent number: 6941927
    Abstract: The invention relates to a method for controlling an internal combustion engine during a cold start operation. The engine is supplied with a substantially constant, lean air/fuel ratio immediately after the engine is started, while the engine has an idle speed that is allowed to vary as a function of the difference between a target air/fuel ratio and an actual air/fuel ratio. The invention further relates to an arrangement for carrying out the method.
