The ADM2000 provides continuous, real time measurements of non-corrosive and nonflammable gas flows. Unlike bubble flowmeters, the ADM 2000 operates without liquids, bubbles or glass parts. The ADM 2000 provides two different types of flow measurement: volumetric flow (ml/min) and mass flow (sccm). Mass flow values are calculated from the volumetric maesurements by correcting for temperature and pressure. The ADM 2000 has flow range of 0.5 to 1000 ml/min.
