Abstract: Energy Economics, Inc.. (EEI) has developed a data-acquisition system for bell provers thai brings information to the prover station thai was previously available only al a mainframe terminal. Information entered at the prover station can be incorporated in an existing data processing system or can be processed as a standalone system on an IBM personal computer. For several years, EEI has had a solid-state controlling system on the market that completely replaces the old electronics for bell provers. The EEI system utilizes a Texas Instruments 510 programmable controller to control the valve sequencing involved in testing a gas meter on a bell prover. A second microprocessor, the Digital Readout (DR), makes the calculations and displays the open and check-run results for the test. The most exciting feature of the DR is its ability to store ASCII data and communicate that information to another computer when prompted. A data acquisition system developed by EEI uses an IBM personal computer for mass storage and processing of meter information as the meters are tested. The information is stored on floppy or hard disk on the IBM PC. The software developed by EEI controls the details of communication, collects and reformats the data for disk storage, then processes the data and presents an organized report. The IBM personal computer is a versatile machine. Other software packages allow it to emulate a terminal on systems by IBM, Texas Instruments, Burroughs, EDC, Honeywell, etc., perform as a spreadsheet with LOTUS 1-2-3, or as a wordprocessor with Wordpro.
