1. 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 product 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 sh

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 the manufacturer or check the latest version of the product manual to obtain accurate data.
2. Flow range of steam vortex flowmeter
The flow range of steam vortex flowmeter varies depending on its model and diameter.
. The diameter (DN) represents the diameter of the pipeline, while the flow range represents the flow value that the flowmeter can measure. The model OW-LU-25 is suitable for DN25 pipelines, with a flow range of liquid 1-10 m ³/h and gas 25-60 m ³/h. For steam flow, it is recommended to refer to the instruction manual. For large pipelines above DN300, it is recommended to use an inserted vortex flowmeter. The model OW-LU-32 is suitable for DN32 pipelines, with a flow range of 1.5-18 m ³/h for liquids and 15-150 m ³/h for gases. The model OW-LU-40 is suitable for DN40 pipelines, with a flow range of 2.2-27 m ³/h for liquids and 22.6-150 m ³/h for gases. The model OW-LU-50 is suitable for DN50 pipelines, with a flow range of liquid 4~55 m ³/h and gas 35~350 m ³/h. The model OW-LU-80 is suitable for DN80 pipelines, with a flow range of 9-135 m ³/h for liquid differential and 90-900 m ³/h for gas. The model OW-LU-100 is suitable for DN100 pipeli
