Electronic Volume Corrector

GasMicroâ„¢ Electronic Volume Corrector

Whether you are on the sending or receiving end of the natural gas distribution system, you want to be assured that the actual value of the transported gas is assessed correctly. While that requires a precise measurement of Btu content, it is just as important to determine the actual volume of gas delivered, corrected for temperature and pressure. That’s not possible with a turbine or rotary flow meter alone.


A Three-In-One Measurement Device is the Most Economical Electronic Volume Corrector on the Market Today

Galvanic’s GasMicro instrument is a three-in-one measurement device that calculates the corrected volume, according to AGA7 and AGA8. The GasMicro device is ideal for both remote-mount and instrument-mount applications. In the former, the turbine and rotary meter sends an electronic signal to the GasMicro instrument that represents the volume of gas that the meter has measured, and then the GasMicro calculates the corrected volume. In the latter, Galvanic’s instrument is mounted directly to the turbine or rotary gas meter through a mechanical instrument drive and the GasMicro instrument generates the electrical signal that represents the volume of gas that the meter measured. It then calculates the corrected volume. In both scenarios, the GasMicro device logs and stores the resulting data in memory for record keeping, and ultimately, for data distribution.
