3. Why is temperature and pressure compensation necessary when measuring gas with a vortex flowmeter?
When measuring gas with a vortex flowmeter, temperature and pressure compensation is needed. The main reasons include the compressibility of the gas, ensuring measurement accuracy, and meeting the requirements of industrial applications. Specifically, the compressibility of the gas is as follows: the gas has a large intermolecular distance and strong compressibility, and its density is significantly affected by temperature and pressure. According to the ideal gas state equation ($PV=nRT $, where $P $is pressure, $V $is volume, $n $is the amount of substance, $R $is the molar gas constant, and $T $is temperature), when the amount of substance remains constant, changes in temperature and pressure will cause changes in gas volume and density. For example, when the pressure increases, gas molecules are compressed, the number of molecules per unit volume increases, and the density increases; When the temperature rises, the volume of the gas expands and the density decreases. This density change directly affects the accuracy of flow measurement.
