What flow meter is better for measuring steam flow?
Steam flowmeter measurement can generally use vortex flowmeter, mainly for gas measurement instruments.. This flowmeter is based on the principle of Karman vortex street. When the fluid flows through a vertically inserted triangular cylindrical generator, an ordered vortex street will be generated behind it. The frequency of these vortex streets is proportional to the flow velocity of the fluid. By detecting the number of these vortex streets, the flow velocity of the fluid can be calculated, and the volumetric flow rate can be calculated based on the diameter of the pipeline. Vortex flowmeter is suitable for measuring high temperature and ultra-high temperature steam because it can withstand high temperature and high pressure environments. In addition, vortex flowmeters have the characteristics of small pressure loss, large range, reliable stability, and no direct contact with the medium. However, the density of steam varies with temperature and pressure, so when measuring steam flow, it is necessary to use a balanced rubber vortex flowmeter with temperature and pressure compensation functions to ensure accurate measurement of the actual amount of steam used. In addition to vortex flowmeters, there are also differential pressure flowmeters that can be used for measuring steam flow. However, differential pressure flow meters are gradually being phased out by users due to high pressure loss, large maintenance requirements, and low accuracy levels. In contrast, vortex flowmeters have significant advantages in measuring steam flow.
