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 flange and other connecting components are also compatible with large-diameter pipelines. In practical applications, when selecting a vortex flowmeter, it is necessary to determine the most suitable size specifications based on specific factors such as pi
2. What diameter is required for PE pipes to ensure a daily water flow of 3000m3?
1、 It is necessary to clarify that the flow is uniform throughout the day; 3000/（24*3600）=0.035m3； 2. Set the flow rate to 1m3/S, R=[0.035 * 4/(3.14 * 1)] ^ 1/2=0.211, which can select a diameter of about 211mm. Choose a 250mm one. Of course, in order to reduce construction costs, you can also recalculate by increasing the flow rate (i.e. increasing pressure). What I have given is only a general data grasp under economic conditions.
3. Vortex steam flowmeter with a diameter of 200, a working steam pressure of 1.8 kilograms, a temperature of 130 degrees, and a speed of 13...
It can be used by Sun. The temperature and pressure of the vortex evaporator and steam flowmeter are adapted to the working state of your medium. The saturated steam at 1.8 kg/cm2 (gauge pressure) should be at 170 ℃, and the flow rate of the steam passing through the flowmeter can be within the range of 5-50m/s (with a clear chain of 5-70 m/s). Your steam weighs 4.06 kg per cubic meter. The working flow rate of DN200 steam vortex flowmeter is 1.92-20.6 tons/hour. So it is feasible to use a DN200 flowmeter to pass 13 tons per hour.
