Abstract
An electronic compact gas meter includes a solid state flow sensor for sensing gas flow rate, data acquisition circuits including an analog-to-digital converter coupled to the sensor for controlling same and providing an output indicative of gas flow, and a digital data processor for receiving the gas flow information from the analog-to-digital converter, processing the information and registering the volumetric gas flow reading at the meter and/or transmitting the volume flow information via RF or telephone communication lines to a remote location.
