How much impact do pressure compensation and temperature compensation in mass flow meters have on the flow rate?
Thread Content
The mass flow meter takes into account the extent to which pressure compensation and temperature compensation affect the volume flow, as well as how they influence the total volume flow.
Gases are compressible when under pressure, and they also expand when heated and contract when cooled; therefore, for any gas, it is necessary to convert values to \"standard conditions\" in order to compare volumes and masses. Go and study it* – start with the ideal gas equation, then move on to the equations for non-ideal gases. Learn about piecewise engineering fitting equations as well. Once you understand this, just plug in the values of temperature and pressure into the equations and calculate by yourself; you’ll be able to see right away just how much of an impact there is. It’s much better than trying to figure things out in the dark, without any clear understanding... :P {:3_51:}
The principle of a mass flow meter is to measure the mass of the medium; as its density changes, its volume also changes
Volumetric flow rate is measured by the flow meter, and neither temperature nor pressure compensation affects the measurement of volumetric flow rate, so it has no impact on it. However, temperature or pressure compensation affects the density, which in turn affects the mass flow rate of the output.
