摘要： A remote meter reading system for example for domestic water meters, operates through an inductive coupling over two lines. A sinusoidal power signal is transmitted from a reader to the meter to power up encoding circuitry in the meter. The encoding circuitry then transmits data by intermittently shorting the input terminals to cause an asynchronous voltage modulation at the reader.

摘要： A flow meter comprising means for receiving a flow of fluid diverted from a mains supply through an inlet and supplying the flow to first fluid conveying means for conveying the flow of fluid to a flow measurement duct, the direction of the flow being reversed in said first fluid conveying means, means for generating a magnetic field across the duct, means for deriving a flow measurement from the voltage induced by said magnetic field in the fluid, and second fluid conveying means for conveying fluid from the measurement duct back to the mains supply through an outlet adjacent said inlet As the meter includes no moving parts, the lifetime of the meter can be significantly longer than that of a displacement meter having an oscillating piston.

摘要： A method of operating an electromagnetic flowmeter comprising a flow measurement duct, means for generating a magnetic field in fluid flowing in the duct across the direction of flow, and means for measuring a voltage thereby induced in the fluid as indicative of the flow, the method comprising measuring an output of said measuring means in the absence of said magnetic field and determining therefrom the presence or absence of fluid in the duct.

摘要： The present invention relates to communication between a device (10) and a remote data processing unit (14). The remote unit may associate with a utility commodity system (9). The remote unit (14) is provided with a connection (26) to a telecommunications system (31). The telecommunications system is adapted to serve a plurality of mobile stations (20). The mobile stations are enabled to communicate with the device (10). In accordance with the disclosed method it is detected that a mobile station is located such that a wireless link may be established between the device and said mobile station. Upon detection of the possibility for communication, information is transmitted between the device (10) and the remote unit (14) via a first wireless link (18) and a second wireless link (21) between the mobile station and the telecommunication system (31). The mobile station is adapted to act as a gateway between the first and second wireless links.
