摘要： A method and system for assessing the condition of a pipeline in a pipeline system is disclosed. The method includes generating a pressure wave in the fluid being carried along the pipeline system at a generation location along the pipeline system, detecting a first pressure wave interaction signal at a first measurement location along the pipeline system resulting from an interaction of the pressure wave with localised variations in the pipeline and then detecting synchronously a second pressure wave interaction signal at a second measurement location along the pipeline system resulting from the interaction of the pressure wave with localised variations in the pipeline. The method then involves comparing the first and second pressure wave interaction signals to determine a location of individual features in the first and second pressure wave interaction signals with respect to the generation location, the individual features corresponding to pressure wave reflections from localised variations in the pipeline and characterising the individual features to assess the condition of the pipeline.

摘要： A turbidity measurement device for measuring turbidity of a fluid flowing in a flow tube. A first transducer transmits ultrasonic signals through the fluid in the turbidity measurement section so as to provide a first ultrasonic standing wave between the first and second section ends. A receiver transducer receives the ultrasonic scattered response from particles in the fluid flowing through the turbidity measurement section. A control circuit operates the transducers and generates a signal indicative of the turbidity of the fluid in response to signals received from the receiver transducer. Preferably, the device may comprise a second transducer for generating a second ultrasonic standing wave with the same frequency, and further the two transducers may be used to generate a measure of flow rate by means of known ultrasonic techniques. This flow rate may be used in the calculation of a measure of turbidity. Both turbidity facilities and flow rate facilities may be integrated in a consumption meter, such as a heat meter or a water meter.

摘要： A method for detecting a fault in a gas supply system for a gas turbine engine. The method comprises: measuring a pressure difference between two gas supplying ducts of the gas supply system; comparing the measured pressure difference to a threshold level; and determining a fault based on the measured pressure difference and the comparison.

摘要： A transportable test system having a control room module, a first IMR test module, and a second IMR test module. The test modules may have fasteners that permit assembly into a unitary package of predetermined overall dimension (i.e. size and shape) such as a standard shipping container dimension. A first IMR test module may have a clean fluid provider and/or supply reservoir, and a second IMR test module may have a used fluid collector and/or collection reservoir. The system may include pressurization, hose restraint, fluid containment, module stabilization/mobilization, lifting, cleaning, and control subsystems.

摘要： 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 17 is continuously wound over the entire length of a flexible tube 1a. Leakage information detected by an optical fiber temperature sensor 21 is transmitted via a terminal 25a to an externally provided temperature measurement device. Meanwhile, when similar leakage occurs in the vicinity of a coupling section 3, the gas pressure inside the heat insulating layer 13a or the like increases due to the pressure of LNG within a corrugated tube 11 or a pressure generated as a result of evaporation of LNG. When the pressure inside the heat insulating layer 13a increases, information representing a change in the gas pressure is transmitted to a terminal 25b via a hollow pipe 27. A tube or the like is externally connected to the terminal 25b, and is connected to a pressure meter or like.
