What are the sizes corresponding to different diameters of vortex flowmeters?

Vortex flowmeters of different diameters correspond to different sizes, and products produced by different manufacturers may have differences in specific dimensions. Taking the common DN25 caliber as an example, its length is generally around 150mm and the outer diameter is about 32mm. The DN50 caliber vortex flow meter has a length of about 200mm and an outer diameter of about 57mm. For DN80 caliber, the length is usually around 250mm and the outer diameter is about 89mm. For DN100 caliber, the length is about 300mm and the outer diameter is about 108mm. When the caliber increases to DN150, the length is approximately 400mm and the outer diameter is about 159mm. The length of a DN200 caliber vortex flowmeter is generally around 500mm and the outer diameter is about 219mm. These dimensional data are only approximate ranges. In practical applications, when selecting a vortex flowmeter, accurate dimensional information should be obtained based on the product manual and specification parameter table provided by the specific manufacturer to ensure correct installation and use.

2. Specifications and models of flow meters

Common specifications and models of different types of flow meters are summarized as follows

1. Vortex flow meters cover different media and flow scenarios, including FS series for industrial gas measurement and micro vortex flow meters for small flow detection

Liquid, with specifications ranging from DN1mm to several meter caliber

4. Mass flow meters, taking the HH series as an example, are divided according to the nominal diameter of the pipeline DN

6、DN

10、DN1

5、DN2p>

5、DN40、DN50、DN80、DN100（ Unit: mm) There are a total of 8 specifications for physical flow meters. Taking EXAIRs 9090 model as an example, it is compatible with 1/2 "to 8" Schedule 40 iron pipes and 25mm to 101mm aluminum pipes, and can support up to 4 "copper pipe air flow measurement. • Vortex/Swirl Vortex Flowmeters: including the conventional DN20-DN200 Swirl Vortex Flowmeters from Astra Instruments and the LUGB series from Chongqing Chuanyi. Ultrasonic flow meters: such as Emerson FLUXUS G721 CA clamp type, Astra ATLS clamp type, and other models.

3. What are the corresponding sizes of various specifications of vortex flowmeters? The size specifications of vortex flowmeters may vary depending on different manufacturers and models. Generally speaking, nominal diameters ranging from DN15 to DN600 or even larger are covered. For vortex flowmeters with smaller diameters such as DN15-DN50, the overall length is relatively short, usually around 150-300mm, and the height and width are also relatively small. Li Huai is suitable for smaller pipeline installation spaces, and its flange size meets the corresponding national standards, making it easy to connect with pipelines. The length of the circular DN80-DN200 vortex flowmeter is approximately in the range of 300-600mm. As the diameter increases, the length, height, and width will also increase accordingly to ensure measurement stability and accuracy. The flange size is also increased according to the standard to match larger diameter pipelines. When the nominal diameter reaches DN250-DN600 and above, the size further increases, and the length may be around 600-1500mm. The overall shape is larger to meet the needs of high flow measurement, and the installation f
