A method and a system for the localization of a mobile WLAN client, located within a WLAN network of multiple WLAN stations. Static reference points are ascertained by measuring field strengths of the WLAN stations at spatial coordinates, aided by WLAN client(s), and assignment of the measured field strengths to the spatial coordinates in terms of data records. Self-learning ascertainment of further dynamic reference points is obtained by measuring field strengths of the WLAN stations, aided by WLAN client(s) moving through the region of the network, and assignment of the measured field strengths in terms of data records to the respective spatial coordinates calculated for this purpose, in the database server. This may be done to localize a WLAN client by selecting a plurality of nearest matched data records of static and dynamic reference points whose subsequently calculated center of gravity corresponds to the estimated position of the WLAN client.

The invention discloses a device and a method for measuring output liquid of a coal bed methane well. The device comprises a buffer vessel, a fluid flowmeter and a connecting pipe, wherein the buffer vessel is provided with an inlet and an output of output liquid, the top of the buffer vessel is provided with a gas outlet, and the bottom of the buffer vessel is provided with a solid phase outlet; the fluid flowmeter and the connecting pipe constitute a U-shaped pipeline, and the fluid flowmeter is at the bottom of the U-shaped pipeline; and two ends of an exhaust pipe are respectively connected with the gas outlet of the buffer vessel and the liquid outlet of the U-shaped pipeline. The method is as follows: after the output liquid of the coal bed methane well is separated by the buffer vessel, the output liquid passes through the flowmeter to be measured. The method enables the liquid to be separated from solid phase coal dust and gas prior to passing through the flowmeter, and only the liquid passes through the fluid flowmeter. Therefore, the measuring accuracy is improved. When the output liquid is small in amount, the physical principle of the U-shaped pipeline is used for improving the measuring accuracy. The measuring method is high in accuracy, can be used for metering the output liquid of the coal bed methane well, the output oil or water in an oil gas well or other similar working conditions.
