Orifice flow meters and vortex flow meters are two commonly used flow measurement instruments, which are widely used in many industrial applications. Although these two flow meters have similar effects in measuring flow, their structures and principles are different, which can also affect their prices.

An orifice plate flowmeter is a flow measurement instrument based on the principle of differential pressure, which consists of an orifice plate, a measuring tube, and a differential pressure transmitter. This type of flowmeter has a simple structure and a relatively intuitive working principle, so it is widely used in flow measurement of small and medium-sized pipelines. However, the manufacturing and installation accuracy requirements of orifice plate flow meters are high, and the requirements for upstream straight pipe sections are also relatively strict, which may increase its manufacturing cost and installation difficulty.

Vortex flowmeter is a flow measurement instrument based on the principle of vortex flow, which uses alternating vortices formed by the fluid in the pipeline to measure flow rate. Compared with orifice flow meters, vortex flow meters have higher measurement accuracy and stability, therefore they have better application effects in large-diameter pipelines and high flow rate fluid measurement. In addition, the installation and maintenance of vortex flowmeter is relatively simple because it does not require special requirements for the upstream straight pipe section.

In terms of price, orifice flow meters are usually cheaper than vortex flow meters. This is because the structure of the orifice plate flowmeter is relatively simple, the manufacturing cost is low, and its installation and maintenance are also relatively easy. In contrast, vortex flow meters have a more complex structure and higher manufacturing costs, but due to their high precision and stability, they are often used in more high-end industrial applications.

In summary, orifice flow meters and vortex flow meters each have their own advantages and disadvantages. When choosing which type of traffic timing, it is necessary to comprehensively consider the actual application needs and budget. If measurements need to be made in large-diameter pipelines or high flow velocity fluids, and high measurement accuracy is required, vortex flow meters may be a better choice.

If the budget is limited and flow measurement is carried out in small and medium-sized pipelines, orifice plate flow meters may be a more cost-effective option.
