RMG presents the TME 400 electronic gas turbine wheel meter

For many years, turbine meters have been the proven workhorses when it comes to measuring the quantity of natural gas in industrial environments and in the utility industry. The measuring principle is sufficiently well known, the design of the devices is comparatively clear (Fig. 1) and accordingly there are various manufacturers on the German and international market. Classical turbine meters convince with their excellent reproducibility and high measuring accuracy. In order to facilitate interchangeability between competitor makes and to establish uniform requirements for the performance of the devices, the design was standardized throughout Europe for the first time in 2007 in DIN EN 12261. Meters that comply with the requirements of this standard in all respects generally also fulfil the conditions for obtaining a type approval valid throughout Europe in accordance with the European Measuring Instruments Directive MID (2014/32/EU) after appropriate tests by a so-called "Notified Body", such as the Physikalisch Technische Bundesanstalt PTB in Germany. This type approval is then a prerequisite for using the meter in commercial transactions. In addition to these standard-compliant versions, more economical, generally more compact designs have established themselves on the market, which are known as quantometers or volumeters (Fig. 2).
