WebMany users choose Coriolis meters for gas flow measurement where measurement accuracy is highly valued. Coriolis flowmeters are available on the market today with accuracies as good as +/-0.35 percent. Higher gas supply pressures help to maintain that high accuracy over a wider turndown than lower pressure applications. Web14 de mai. de 2006 · The N stands for Normal. It means it was measured at standard temperature and pressure. Because the volume of gasses change with temperature or pressure, it is necessary to specify the temperature and pressure the flow rate was measured at. Standard pressure is 1 atmosphere. Standard temperature varies between …
