Vortex flow meters are primarily used for measuring the flow rate of gases, liquids, and steam. They operate by utilizing the principle of fluid oscillation to determine flow rates. As the fluid passes through the vortex flow transmitter in the pipeline, two rows of vortices proportional to the flow velocity are generated alternately above and below the vortex generator shaped like a triangular prism. The frequency at which these vortices are released is related to the average velocity of the fluid flowing past the vortex generator as well as the characteristic width of the vortex generator. Next, let’s take a look at the advantages of vortex flowmeters in gas measurement. The advantages of vortex flowmeters for gas measurement include: a simple and robust structure, no moving parts, high reliability, and excellent performance over long periods of operation. It is easy to install and very convenient to maintain. The detection sensor does not come into direct contact with the medium being measured, offering stable performance and a long service life. The output is a pulse signal proportional to the flow rate, with no zero drift and high precision. It has a wide measurement range, with a range ratio of up to 1:10. It has low pressure loss and low operating costs, making it more energy-efficient. Flow metering is one of the components of measurement science and technology, and it is closely related to the national economy, national defense construction, and scientific research. Doing this job well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today’s era of energy crises and increasing automation in industrial production, the significance and role of flow meters in the national economy have become even more evident.
