摘要: Methods and apparatus for detecting and measuring gas flow are disclosed in which lidar distance information, acquired during the detection of gas using a lidar sensor, is used together with prevailing wind data to determine local wind data for the leak location. This local wind data, which may comprise one or more vectors or a 3D wind model, is used in the determination of flow rate.

摘要: A method and system for leakage status evaluation and leaks location of a solid waste land disposal facility. The method includes: arranging an off-site emitting electrode for the solid waste land disposal facility, and arranging a plurality of intra-site receiving electrodes on a solid waste pile surface in a grid shape; selecting a power supply to collect a current value between the off-site emitting electrode and each of the intra-site receiving electrodes respectively, and determining a maximum current value point Mn of the solid waste pile surface and a maximum current value An; selecting an off-site point So2, and measuring a current value between the off-site emitting electrode and the point So2 as a reference current Ab under the same power supply condition; and determining a leakage status of the solid waste land disposal facility based on a ratio of the maximum current value An to the reference current Ab.

摘要: An integrity monitoring system for a lined pipeline is provided for monitoring the integrity of a polymer liner in a host pipe. Methods and apparatus are described by which a lined pipeline is provided with such an integrity monitoring system. Sensor cable is able to bridge a joint between sections of lined pipe, for example by routing the sensor cable across the joint via a channel in an electrofusion fitting or by connecting successive lengths of sensor cable via pass-throughs in an electrofusion fitting. Advantageously, the sensor cable is disposed within a continuous annulus between linings and host pipes, and the continuous annulus is maintained across pipe joints using electrofusion fittings.

摘要: A hydrogen sensor includes a communication terminal, a plurality of identification terminals, and an ID setting section. The communication terminal is connected to a first communication bus or a second communication bus, and communicate with a vehicle ECU. Each of the plurality of identification terminals is set to either an open state (OPEN) in which the identification terminal is not connected to any potential or a grounded state (GND) in which the identification terminal is connected to a ground potential. The ID setting section sets an identifier in either a standard format or an extended format, according to a difference in the communication bus to which the communication terminal is connected.

摘要: A liquid-leakage detection device includes a detection belt body, an electrode, a first connection member and a second connection member. The detection belt body is configured to wrap an outer surface of a to-be-detected device. The electrode is configured to detect whether the to-be-detected device leaks liquid. The electrode is connected to the detection belt body and disposed on one surface or inside of the detection belt body. The first connection member connected to a first side of the detection belt body and includes at least one first buckling part. The second connection member is connected to a second side of the detection belt body and includes at least one second buckling part. The second buckling part is capable of buckling with the first buckling part so that the first connection member is connected to the second connection member by buckling.

摘要: A water heater includes a tank assembly that defines an insulation cavity between an inner storage tank and an outer jacket. The water heater includes a bottom pad that supports the tank assembly thereon. The bottom pad is disposed in a bottom pan. Gaskets are disposed between the bottom pad and the bottom pan of the water heater. The bottom pad and at least one of the gaskets include apertures that are configured to internally route a leak sensor assembly of the water heater from the bottom pan to a controller of the water heater through the insulation cavity while preventing a leak of insulation material from the insulation cavity to the bottom pan. The water heater also includes a mounting bracket that is coupled to the inner storage tank to securely hold and route a portion of the leak sensor assembly disposed in the insulation cavity to the controller.
