1. For DN250 pipelines, the size of the flow meter to be installed mainly depends on your flow rate. Flow meters have specification parameters, whether it is glass rotors, metal floats, vortex streets, electromagnetic flow meters, etc. The main data of the instrument design is mainly determined by flow rate, medium characteristics (such as liquids, gases, corrosivity, conductivity, etc.), temperature, pressure, installation method, working conditions, economic conditions, and other comprehensive factors. The selection of flow meters is a science, so it is not easy to use any flow meter to adapt to 250 pipelines. When the flow rate is insufficient and sold indiscriminately, the diameter can be changed (by reducing or expanding the pipe diameter connected to the flow meter). Please complete the data according to the above requirements in order to make a scientific selection. 2. Technical parameters of vortex flowmeter? Kneeling for vortex flowmeter parameters

3. 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.
4. What are the brands of instruments for measuring fluid flow on pipelines?
The brands of instruments for measuring fluid flow on pipelines are divided into two camps: high-end foreign brands and mainstream domestic brands, covering a full range of flowmeter application sce
