With these series, the transition to the digital age for classic turbine meters used in custody transfer applications has been successfully completed: The meter movements comply with DIN/EN12261 in terms of metrological performance and overall length, which is a prerequisite for custody transfer approval. However, the simple electronic totalizer of the TME400-VMF or the integrated volume corrector of the TME400-VCF now provide the modern communication options, especially Modbus communication. The RMGViewTME software enables not only the parameterization of the devices but also the visualization of all measured data in trend graphics and also the readout of the integrated measured value and event archives.
