digital vortex flowmeter

In industrial process control, energy measurement and gas/liquid flow monitoring, vortex flowmeters have become an important choice for flow measurement due to their advantages such as simple structure, wide range and high stability. However, in the face of different working conditions and application requirements, how to make the correct selection is of vital importance. This article will start from the key parameters to provide you with a detailed analysis of the selection points of vortex flowmeters, helping you achieve the best configuration.

Due to the compressibility of the gas, its flow measurement is more complex than that of the liquid, and the output signal of the vortex flowmeter is related to the gas density in addition to the input signal, and the density of the gas is a function of temperature and pressure (referred to as temperature and pressure).

Intelligent vortex flowmeters can measure air. Vortex flowmeter is a new flowmeter for flow measurement based on Karman vortex principle. It has good medium adaptability and can directly measure the volume flow of various media (including air). When measuring air, the vortex flowmeter generates regular vortices through the triangular column vortex generator set in the fluid, and the frequency of these vortices is proportional to the average velocity of the measured medium, so that the air flow can be calculated.
