Apparatus for correcting measured gas flow |
摘要 |
A gas flow volume corrector mounted on a flow meter is provided with a microprocessor which calculates a corrected volume each time the meter measures a unit volume of flowing gas. Customer supplied data as to base conditions, specific gravity and gas composition are utilized to calculate supercompressibility values. These values are then processed to provide a plurality of constants which define calculation equations. The constants are stored in the corrector on a diode matrix card or PROM and are utilized each time the meter measures a unit volume of flowing gas for calculating the corrected volume. To conserve memory space, integer arithmetic, rather than floating point arithmetic, is utilized in the calculations.
