  • Patent number: 10429261
    Abstract: The invention provides a pressure sensor device arranged for measuring a pressure in a fluid pipe system, e.g. a utility network. A measurement system with a pressure sensor serves to measure pressure in the fluid pipe system, and a data processing unit determines at least one statistical parameter in response to a plurality of pressure measurements. Data packets with the statistical parameter is then transmitted by means of a communication module, e.g. via a data network which serves for remote reading of utility meters. The statistical parameter is selected from the second, third and fourth statistical moments of the pressures measured with the plurality of measurements of pressure. The pressure sensor device in a battery driven form can be placed at remote locations in a fluid pipe system to monitor pressure transients, e.g. in a water distribution system.

    Abstract: The present invention refers to a method wherein a test body is assembled in specific configurations to be submitted to testing in a conventional hydrostatic chamber. The method calls for assembling a test body that simulates cementing failures, the presence of stress anisotropy and a borehole of irregular geometry, by pressurizing said test body in a conventional hydrostatic chamber. The uniform forces are distributed circumferentially around a casing stream in a non-uniform way, simulating operating conditions that are as close as possible to reality, enabling an analysis of how the structure reacts in scenarios similar to actual conditions.

  • Patent number: 8893542
    Abstract: A method and apparatus for monitoring and determining fuel vapor recovery performance is disclosed. The dispensing of liquid fuel into a tank by a conventional gas pump nozzle naturally displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispensing point nozzle by a vapor recovery system. A properly functioning vapor recovery system recovers approximately one unit volume of vapor for every unit volume of dispensed liquid fuel. The ratio of recovered vapor to dispensed fuel is termed the A/L ratio, which should ideally be approximately equal to one (1). The A/L ratio, and thus the proper functioning of the vapor recovery system, may be determined by measuring liquid fuel flow and return vapor flow (using a vapor flow sensor) on a nozzle-by-nozzle basis. The disclosed methods and apparatus provide for the determination of A/L ratios for individual nozzles using a reduced number of vapor flow sensors.

  • Patent number: 8479565
    Abstract: Provided are a fluid conveying tube and a fluid leakage detecting system which can convey a cryogenic fluid such as LNG and which can quickly and reliably detect leakage of the fluid within the tube and the position of the leakage. An optical fiber is continuously wound over the entire length of a flexible tube. Leakage information detected by an optical fiber temperature sensor is transmitted via a terminal to an externally provided temperature measurement device. Meanwhile, when similar leakage occurs in the vicinity of a coupling section, the gas pressure inside the heat insulating layer or the like increases due to the pressure of LNG within a corrugated tube or a pressure generated as a result of evaporation of LNG. When the pressure inside the heat insulating layer increases, information representing a change in the gas pressure is transmitted to a terminal via a hollow pipe. A tube or the like is externally connected to the terminal, and is connected to a pressure meter or like.

  • Patent number: 8342006
    Abstract: The invention relates to a method for detecting and/or quantifying water leaks in a water pipe, and to a device for realizing said method. The method of the invention comprises measuring the water flow rate in the pipe in at least two different locations, i.e., one downstream and one upstream relative to the suspected leak, the water flow rate being measured by injecting a tracing agent that modifies the water conductivity instantaneously at an upstream location and a downstream location relative to the suspected leak location, continuously measuring the water conductivity downstream from said locations and, from the conductivity values, calculating the water flow rates upstream and downstream relative to the suspected leak location in the pipe. The method of the invention can be used for quantifying a leak flow rate that can even be a very small one.

  • Patent number: 8327689
    Abstract: A method and apparatus for monitoring and determining fuel vapor recovery performance is disclosed. The dispensing of liquid fuel into a tank by a conventional gas pump nozzle naturally displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispensing point nozzle by a vapor recovery system. A properly functioning vapor recovery system recovers approximately one unit volume of vapor for every unit volume of dispensed liquid fuel. The ratio of recovered vapor to dispensed fuel is termed the A/L ratio, which should ideally be approximately equal to one (1). The A/L ratio, and thus the proper functioning of the vapor recovery system, may be determined by measuring liquid fuel flow and return vapor flow (using a vapor flow sensor) on a nozzle-by-nozzle basis. The disclosed methods and apparatus provide for the determination of A/L ratios for individual nozzles using a reduced number of vapor flow sensors.

  • Patent number: 8240191
    Abstract: The present invention is directed to a Universal Power Platform (UPP) that powers the pump or pumps that may not be on the platform but that are in a skid subsea near the pipeline for a desired pre-commissioning method to be carried out, such as cleaning, filling, chemical treating, pigging, hydrostatic testing or dewatering the pipeline. The UPP is suspended from a vessel by an umbilical that provides the electric power for running the selected pump(s). The Power Platform also is used as a testing system for control umbilicals that usually are near the pipelines.

  • Patent number: 8234911
    Abstract: In a method for detecting a leak in a double pipe, a medium located in an intermediate chamber between the interior and exterior pipe is moved toward a first end of the pipe, whereupon the medium flows in from the second end. On the first end the medium is examined for any leakage of a characteristic material, upon the detection of which a leakage signal is generated and a location of the leakage is calculated based on the transport time of the characteristic material from the leakage to the first end and on the mass flow of the medium. A corresponding device contains a conveyor unit for moving the medium through the intermediate chamber. A material sensor is disposed at the first end for examining the medium for the characteristic material. A control and analysis unit is provided for generating a leakage signal and calculating the location of the leakage.

  • Patent number: 8210029
    Abstract: A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position.
