  • Patent number: 4940976
    Abstract: An automated multi-purpose utility water meter readout system. The disclosed system obtains water usage information from an existing water meter without any modifications or attachments to the meter. The device needs only to be located in proximity to the water meter and obtains water flow information by sensing the magnetic flux lines generated by the internal rotating coupling magnets of the water meter. The varying magnetic flux is converted to a periodic electrical signal whose frequency is proportional to the flow rate. The instantaneous flow is continually totalized and stored in a solid-state counter, from which the totalized flow information is periodically transmitted to a remote receiver by a standard, well-proven radio frequency telemetry link. The remote receiver stores data from multiple meters (up to 10,000) and periodically sends the data to the data processing office by means of telephone lines, CATV cable, or RF link.
