WebGas Flow Measurement. Gases are compressible and change volume when placed under pressure or are heated or cooled. A volume of gas under one set of conditions (pressure and temperature) is not equivalent to the same gas under different conditions. Gas flow can be measured in volumetric or mass flow rates (such as litres per second or kg/s). WebFor the adult and pediatric respiratory modes, the threshold is set to 3L/min and 1L/min respectively. For the automatic respiratory mode, the threshold is automatically set based on the measured tidal volume. The flow is considered stable if it does not change quickly. This means that the flow must not change more than 0.4L/min during the plateau. WebFor natural gas flow measurement and control applications, FCI provides an extensive selection of solutions.
