RMG by Honeywell ERZ 2000-NG flow computer and gas volume corrector

The ERZ 2000-NG flow computer and gas volume corrector from RMG by Honeywell is designed to provide a reliable and more intuitive solution for natural gas volume conversion in fiscal and secondary metering applications.

Featuring a graphical touch screen user interface, the flow computer enables gas distribution, transportation and storage service organisations to accurately measure gas flow, correct the measured volume, calculate energy consumption and provides all data via standardised protocols. It is certified by the European Measuring Instruments Directive (MID) as a gas volume and calorific value corrector for custody transfer metering of natural gases. The unit can easily be integrated in a gas train application in a cabinet along with gas chromatographs, flow computers, data loggers and controllers.

The device performs gas volume conversion on the basis of the equation-of-state for ideal gases. Since this equation alone does not meet all the requirements for high-precision gas metering, the gas volume corrector also takes into account the characteristics of the real gas by using the K coefficient as a correction factor. Such an approach is said to ensure utmost measurement accuracy and repeatability.

Designed as a universal instrument, it can be used for all metrological tasks in a gas metering station. It is available in a choice of system configurations, including: ERZ 2002-NG Density Volume Converter, ERZ 2004-NG State Volume Converter, ERZ 2104-NG State Calorific Value Volume Converter, ERZ 2102-NG Density Calorific Value Volume Converter and ERZ 2014/2114-NG Effective Pressure Gas Meter.
