Fluid Pressure Gauge Patents (Class 73/700)
  • Patent number: 11708943
    Abstract: A pre-alarming method, a control method, and a control system for a harmful flow pattern in an oil and gas pipeline-riser system are provided. Support vector machines are trained. Through at least three pressure difference signals on the pipeline-riser system, an overall flow pattern in the pipeline-riser system is continuously and rapidly identified. Depending on monitoring on formation of a long liquid slug in a seabed pipeline and a quick response of the mean value of each pressure difference signal on a flow rate change, pre-alarming for a liquid slug caused by different mechanisms is realized, and liquid slug formation positions respectively of seabed pipeline and riser bottom are correspondingly pre-alarmed; after a pre-alarm is issued, there is enough time for a control device to respond, so as to avoid formation of the harmful flow pattern or damages caused by the harmful flow pattern.

  • Patent number: 11698044
    Abstract: A fuel tank system includes a fuel storage unit, a processing unit, and a control unit. The control unit performs a first failure diagnosis of diagnosing a failure of the fuel storage unit in a state where the sealing valve is closed. When the control unit diagnoses that the fuel storage unit is normal, the control unit performs a second failure diagnosis of diagnosing a failure of a purge valve and a bypass valve by causing a pressure generation unit to generate pressure in a state where the sealing valve is closed. When there is a possibility that the purge valve and the bypass valve are in closed-sticking, the control unit performs a third failure diagnosis of specifying a failure in any one of closed-sticking of the purge valve and closed-sticking of the bypass valve by opening the sealing valve.

  • Patent number: 11287293
    Abstract: A sensor apparatus has a sensor protruding portion and a sensor support which are formed integrally with each other. The sensor apparatus also includes a retainer, an inner seal, an outer seal, a fastener, and a friction reducer. The retainer is rotatable relative to the sensor protruding portion and the sensor support. The inner seal is disposed between the sensor support and the retainer. The outer seal is disposed between a wall and the retainer. The fastener includes a fitting groove formed in one of the sensor support and the retainer and a protrusion formed on the other of the sensor support and the retainer. The protrusion is engaged in the fitting groove to achieve installation of the sensor apparatus in the wall. The friction reducer works to increase an interval between the sensor support and the retainer to reduce a degree of friction produced by the inner seal when the sensor support is turned relative to the retainer to install the sensor apparatus in the wall.

    Abstract: Systems and methods for measuring air speed which solve the problem of icing or blockage by creating an exterior surface on an aircraft that channels air and measures the pressure difference of the pressure through the airflow and the static pressure. This exterior surface cannot be blocked easily because air is always flowing when the aircraft is in motion, any external matter that could be on the exterior surface is readily visible, and the exterior surface can be heated to prevent icing. In addition, the exterior surface is made of a flexible material that is able to conform closely to the exterior shape of the aircraft. The preferred embodiments comprise microelectromechanical system pressure sensors placed under the air channels for measuring the pressure difference in each channel and an air speed processor for transforming the pressure differences into an air speed estimate.

    Abstract: A closed-loop regulation method of a ventilation system using a control computer. The method includes the steps comprising: providing a ventilation system with a control computer, an exhaust fan, sensors, and gates; using the sensors to determine actual air velocities within the ventilation system; providing minimum air velocities that must be maintained throughout the ventilation system; monitoring the one or more air velocities; and maintaining by the control computer that the actual air velocities are above the one or more minimum air velocities. Preferably, the ventilation system includes a control computer that takes the measurements, makes the air flow calculations, and automatically adjusts the gates and fans to ensure that a minimum air velocity is kept in all parts of the ducts of the system. Preferably, the ventilation system is energy efficient by optimizing the air flow and lowering the amount of energy needed to run the system.

  • Publication number: 20140356165
    Abstract: A wind turbine blade has a suction side shell member and a pressure side shell member. The shell members are joined along a leading and trailing edge from a root to a tip of the blade and defining an internal cavity of the blade. A pressure sensor is configured on at least one of the suction or pressure side shell members. The pressure sensor further includes a body mounted to an inner surface of the respective shell member within the internal cavity. A sensing element has a first side exposed to external air pressure through a passage in the respective shell member, and an opposite second side exposed to a reference pressure. Control circuitry within the body generates a variable output signal as a function of a pressure differential between the external air pressure and reference pressure experienced by the sensing element.

    Abstract: Apparatus that detects the pressure of water that can move through a water channel (26) towards and away from a pressure sensor (22), wherein the apparatus is constructed to avoid damage from freezing water. The water channel is constructed with a narrow channel portion (40) and a wide channel portion (42) connected in series, with the narrow channel portion lying closer to the pressure sensor. When the ambient temperature falls below the freezing temperature of water, water in the narrow channel portion freezes before water in the wide channel portion freezes, and frozen water in the narrow channel portion acts like a plug to prevent water (or ice) from moving toward the pressure sensor.
