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. Flow range of vortex flowmeter

The flow range of vortex flowmeter is mainly determined by the sensor diameter and fluid properties. The larger the diameter, the wider the measurable flow range.

. The conventional liquid measurement range is between 0.5m/s and 7m/s flow rate, and the gas measurement range is between 5m/s and 60m/s. 1. Correspondence between caliber and flow rate (under normal temperature water conditions) The flow range is directly related to the instrument caliber, and the following are typical parameters (referring to the pro DN100 Vortex Flow Meter

duct manuals of mainstream domestic manufacturers such as Chuanyi and Ganges in 2023): • DN15: minimum about 1.2 m ³/h, maximum about 15 m ³/h • DN25: minimum about 3 m ³/h, maximum about 40 m ³/h • DN50: minimum about 10 m ³/h, maximum about 150 m ³/h • DN100: minimum about 40 m ³/h, maximum about 650 m ³/h • DN200: minimum about 150 m ³/h, maximum about 2500 m ³/h • DN300: minimum about 300 m ³/h, maximum about 5500 m ³/h. 2. Influence of fluid medium • Liquid measurement (Water, oil, etc.): The flow rate range is usually 0.5-7 m/s, and liquids with viscosity higher than 30cP will significantly increase the measurement lower limit. Gas measurement (air search, steam, etc.): The flow rate range is usually 5-60 m/s, and low-pressure gases may have an increased lower limit flow rate due to low density. • Steam measurement: It is necessary to distinguish between saturated steam and superheated steam, and the flow range should be calculated based on temperature and pressure compensation to determine the actual mass flow rate. Avoid long-term use below the lower limit of 20%, otherwise the signal stability will deteriorate and errors will increase. • The maximum flow rate shall not exceed 120% of the upper limit value of the instrument to avoid damage to the vortex flowmeter.

4. The extended range ratio of the standard vortex flowmeter is 1:10~1:15, and models using dual sensors or digital signal processing technology can be extended to 1:20~1:30 (such as Emerson high-precision models), but the price is higher. The actual selection should be strictly based on the calculation of medium operating parameters (temperature, pressure, density, viscosity). It is recommended to directly use the selection software provided by t
