摘要： A method and an apparatus for determining leakage volume of fluid in transportation pipelines are provided. The method comprises: obtaining the negative pressure wave signals detected by at least two pressure sensors arranged on the pipeline; determining the pressure signal at the leakage location based on the negative pressure wave signals; determining the leakage rate during a leakage period based on the pressure signal at the leakage location according to a leakage model; and determining the leakage volume of the fluid in the pipeline based on the leakage rate and the leakage period. The apparatus provided corresponds to the method described above. By using the method and apparatus described above, the leakage volume of the transportation pipelines can be obtained to help understand the leakage profile of the pipelines and thus reduce losses (FIG. 1).

摘要： An apparatus and method for a fluid leak detection and shutdown for a fluid distribution system having a total system flow rate. The apparatus includes a solenoid shutoff valve having a normally open state and an activated closed state with a flow capacity matched to the total fluid distribution system flow rate. The apparatus also has a primary fluid flow line and a smaller capacity secondary fluid flow line. The apparatus includes a flow sensor in fluid communication with the secondary fluid flow line, wherein the flow sensor has a perceptible output and a flow rate capacity less than the solenoid shutoff flow capacity. Operationally, the flow sensor receives a portion of the solenoid shutoff valve flow capacity in priority over the primary fluid flow line, allowing the flow sensor to detect minimal flow rates and using the perceptible output to activate the solenoid shutoff valve into the closed state.

摘要： This application relates to methods and apparatus for monitoring of conduits, especially oil or gas pipelines, as an object such as pipeline pig moves within the conduit. The method comprises monitoring at least part of a conduit (206) using a fibre optic (202) distributed acoustic sensor (204) as the object (208) passes along the conduit. The acoustic signals detected from at least one sensing location (203) as the object moves along the conduit are analysed so as to discriminate acoustic signals received at said sensing location from different locations. The method allows the contributions to the acoustic signal at a given sensing portion from different locations to be separately identified, and can allow the detection of the location of acoustic sources along the conduit even if the source is outside the section of conduit which is monitored. The method provides a method of leak detection that can extend the monitoring of the pipeline beyond the location of the optical fibre.

摘要： An intelligent water flow control system is coupled with a main water flow source and controls the water flow by controlling an electrical valve in line with the water source and making a determination by receiving information from one or more water flow detectors. The system controller executes that software which issues information from the one or more flow detectors and output signals for controlling the open or closed state of the various valves. The software makes determinations on whether a leakage condition is present and issues the valve control signals to shut off the necessary valves and to report to a user, the occurrence of a leakage condition.

摘要： A water leak detection and prevention system uses sensors, wires, and wireless transmitters, to monitor all plumbing fixtures (faucets, toilets, hose bibs, etc.) and water-using appliances (dishwashers, washing machines, icemakers, etc.). When water is being used at a plumbing fixture or a water-using appliance, the sensor shows water that is expected to be used at that location and communicates the usage and the amount of flow for that location. Excessive usage or flow, or any flow when a location has not called for water, is indicative of a leak. Water to the building is on all the time—water pressure remains in the plumbing—creating no delay in water delivery. Water pressure and water flow are monitored at all times whether water is off or on. Should a leak occur the water flow sensor will show that water is flowing and that no approved location has called for water. The main valve will immediately be turned off and water in the plumbing system will be purged safely outside the building. Plumbing system protection: Should an over-pressure situation occur—due to expanding water being heated for instance—system will evacuate a small amount of water to the outside of the building, protecting plumbing, fixtures and appliances. Temperature sensors placed on piping at strategic locations will protect plumbing from freezing. Should temperatures near the freezing point, the system will purge water from the pipes. Water conservation system: should a toilet flapper become stuck open or partially open, or a faucet left dripping or running, the system main valve will close and water will be conserved.

摘要： A method and apparatus for detecting and preventing electrically induced fires in a gas tubing systems constructed of Corrugated Stainless Steel Tubing (CSST) and Gas Appliance Connectors (GAC). The system of the present invention may include one or more energy detection schemes to detect electrical energy surges on the gas line. When such a surge is detected, the control circuitry of the present invention causes an electric two-way main gas valve to de-energize into a position wherein the flow of gas from a gas feeder pipe to the gas tubing system is blocked and residual gas pressure in the gas tubing system is automatically vented to the atmosphere.

摘要： Detecting a leak, or the like, with high accuracy on the basis of pressure and a flow volume acquired during use of fluid is made possible.A volume of gas flowing through a flow path 102 is measured by a flow volume measurement unit 106, and pressure is measured by a pressure measurement unit 108. Measured flow data and measured pressure data are input to an analysis unit 112, to thus analyze following of a pressure change by a flow volume change. An amount of flow volume change responsive to an amount of pressure change of a predetermined level or more is classified into a plurality of ranges by means of a predetermined threshold value, and a following flow value change is determined on the basis of determination conditions of the respective ranges of amounts of flow volume changes.

摘要： Methods and apparatus for tracking objects in conduits, especially for tracking the movement of a pig in a pipeline, are disclosed. Distributed acoustic sensing is used to obtain signal returns from a plurality of discrete longitudinal sensing portions of a fibre optic cable which is laid along the length of the conduit. The method involves detecting an acoustic signature corresponding to the object moving in the conduit. The acoustic signature may comprise a series of pressure pulses caused by the object traversing joints etc. in the conduit. Preferably the method involves detecting pressure waves caused by the object as it moves through the conduit. Detecting the characteristic pressure wave signal provides discrimination of the object from other acoustic disturbances. In pipeline applications a pig can be tracked in real time, if the pig stops moving an alert can be generated and the location of the pig will be known.
