1. 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 pipelines, with a flow range of 14-200 m ³/h for liquids and 140-1400 m ³/h for gases. The model OW-LU-150 is suitable for DN150 pipelines, with a flow range of 32-480 m ³/h for liquids and 300-3000 m ³/h for gases. The model OW-LU-200 is suitable for DN200 pipelines, with a flow range of 56~800 m ³/h for liquids and 550~5500 m ³/h for gases. Based on the above information, you can choose a suitable steam vortex flowmeter according to your pipeline diameter and understand the flow range it can measure. The steam vortex flowmeter is mainly used for measuring the flow rate of steam medium fluid in industrial pipelines. The characteristics of steam vortex flowme

2. What flowmeter is used to measure superheated steam/saturated steam? Vortex flowmeters are generally used to measure superheated steam and saturated steam. To ensure measurement accuracy, appropriate temperature or pressure compensation should be selected based on the characteristics of both. Saturated steam: Water is heated at a certain pressure until it boils and vaporizes. At this point, the steam temperature is equal to the saturation temperature, which is called saturated steam. The saturation pressure and saturation temperature correspond to each other, and both pressure compensation and temperature compensation can be used during measurement. Due to the relatively easy pressure compensation and high measurement accuracy, pressure compensation methods are mostly used in practical applications, such as the use of LUB split vortex flowmeter embedded with HSYB pressure transmitter. Overheated steam: Saturated steam continues to be heated, and when the temperature rises and exceeds the saturation temperature at that pressure, it is called superheated steam. Superheated steam is a single-phase fluid with characteristics similar to gases. Its temperature and pressure are two independent variables, and its density is determined by both. When measuring, any change in temperature or pressure can cause a change in steam density, which in turn affects the mass flow rate. Therefore, temperature and pressure compensation must be performed simultaneously to ensure accuracy, such as when using a LU
