Can a DN200 caliber vortex flowmeter measure steam?
The DN200 vortex flowmeter refers to the diameter of the flowmeter, which also refers to the judgment of whether the pipeline diameter is large or small. The flow range of gas measured by the DN200 vortex flowmeter is between (0-5000) m3/h, and steam can be measured using the DN200 vortex flowmeter as long as it is within this measurement parameter range.
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 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
3. Selection of Superheated Steam Flow Meter
The selection of superheated steam flow meters should comprehensively consider the pipe diameter, maximum temperature, maximum pressure, flow range, and measurement accuracy. Common types include vortex street, bend pipe, V-cone, and orifice plate. Among them, vortex street and bend pipe are more suitable for high temperature and high pressure scenarios, while orifice plate and V-cone are less commonly used due to accuracy and pressure loss issues.
. The specific selection suggestions are as follows:1. Common types and characteristics: Vortex flowmeter is suitable for scenarios where the pipeline is less than DN300 and the temperature is ≤ 450 ℃. A temperature pressure compensation integrated design should be adopted to ensure accurate measurement. According to user needs, integrated or split type instruments can be selected, and the instrument diameter can be determined based on the steam consumption of pipelines and equipment. The installation method is flexible (horizontal or vertical), but it needs to mee
